ises.org

The ISES website (ises.org) is the online home of the International Solar Energy Society, a global organization focused on advancing renewable energy. The site primarily offers four types of content: a peer-reviewed journal (Solar Energy), a regular column in pv magazine, conference and event announcements (such as EuroSun), and membership information for individuals and organizations. It is a resource for researchers, industry professionals, and anyone tracking solar energy research and policy developments rather than a consumer how-to site.

Research Publications: The Solar Energy Journal

The site regularly announces new volumes and parts of the Solar Energy journal, which publishes solar energy research. Recent listings on the homepage include:

• Volume 315, Part 1 and Part 2
• Volume 314, Part 1 and Part 2

Each announcement links to the latest research featured in that issue. If you follow academic or technical developments in solar energy, these posts serve as a running index of new peer-reviewed work.

Columns and Blog Posts in pv magazine

ISES publishes a recurring column in pv magazine, and the website links to each installment. Recent examples from the homepage show the range of topics:

These columns are short, topical analyses of policy, markets, and technology rather than original research papers.

Events: EuroSun Conferences and Webinars

The site carries announcements for ISES-organized events, including:

• EuroSun conferences — for example, the EuroSun2028 call for expressions of interest (reported as closed), planned by ISES and the IEA Solar Heating and Cooling Programme.
• Webinars — listed in the site navigation alongside publications and blog posts.

If you want to present work, attend, or track conference deadlines, this section is the place to check.

Membership and Community

The site invites individuals and organizations to join the "global solar community." It lists Corporate and Institution Members and Partners, and describes ISES as "the global voice for renewable energy," driving the transition to a 100% renewable energy future. Membership pages are the entry point if you want to participate in the society rather than just read its output.

Is It Worth Following?

• Yes, if you want a single feed of solar research releases, short policy/market commentary, and conference news from an established international society.
• Less useful if you are looking for practical installation guides, product comparisons, or consumer pricing information — the site's content is oriented toward research, policy, and community news.

The homepage also includes a search function and a user login, suggesting that some content or member services may sit behind an account; the available material does not specify what those restrictions are, so check directly if you need member-only access.

To join ISES, use the "Become a Member today" call-to-action on the ises.org homepage, which leads into the "Join Our Global Solar Community" sign-up path. If you already have an account, member resources are reached through the "User login" link on the same page. The site separates individual membership from Corporate and Institution Members, so pick the track that matches you before starting.

What the homepage actually offers

The ISES homepage presents itself as "The global voice for renewable energy" and is organized around a few clear entry points:

• Become a Member today — the primary join prompt, paired with the line "The future is bright, and we want YOU to be part of it!"
• Join Our Global Solar Community — the continuation of the membership pitch, aimed at "passionate individuals" who want to help lead the transition to a 100% renewable energy future.
• User login — the access point for existing accounts.
• Corporate and Institution Members — a distinct section for organizational membership rather than individual sign-up.
• Partners — a separate listing for partner organizations.

Around these, the page carries ISES news and publications: the Solar Energy Journal volumes, the monthly ISES column in pv magazine, EuroSun conference updates (including EuroSun 2026 and the closed EuroSun 2028 call for expressions of interest), and webinars.

Joining as an individual

1. Open ises.org and locate the "Become a Member today" prompt near the "Corporate and Institution Members" area of the homepage.
2. Follow the "Join Our Global Solar Community" path to reach the membership sign-up.
3. Complete the registration with your details and submit.

Expected result: you receive an ISES account that you can then use at the "User login" link. The homepage does not publish membership fees, tier details, or payment methods, so treat pricing and any login restrictions as things to confirm on the membership pages themselves rather than assuming free access.

Joining as an organization

If you are registering on behalf of a company, university, or institution, start from the Corporate and Institution Members section instead of the individual join prompt. That section is the organizational track; the individual "Join Our Global Solar Community" language is addressed to individuals. The homepage does not list the requirements or benefits for corporate members, so check that section directly before committing.

Accessing member resources

Existing members should use User login on the homepage. Once signed in, member-only material becomes available; the homepage itself only shows the login entry, not what sits behind it. If you are not yet a member, the login will not give you member content — join first, then log in.

What you can read without joining

A substantial amount of ISES content is visible on the public site and is worth knowing before you decide on membership:

Use these public pages to judge whether the society's focus — solar research, storage, and the renewable transition — matches your interests before you join.

Common sticking points

• Wrong track: Organizations that start from the individual join prompt may end up in the wrong membership category. Begin at "Corporate and Institution Members" if you are signing up an entity.
• Expecting instant access: The login link only works for accounts that already exist; joining and logging in are two separate steps.
• Assuming cost or access terms: The homepage gives no pricing or access conditions. Confirm fees, member benefits, and any login limitations on the membership pages rather than inferring them.
• Looking for a menu you can't see: The homepage's join and login prompts sit alongside the member and partner sections; if a link seems missing, return to the homepage rather than hunting through news articles.

ISES is the International Solar Energy Society, a global membership organization that describes itself as "the global voice for renewable energy." Its website, ises.org, is the public face of that mission: a place to follow solar energy research, read news and commentary, learn about conferences and webinars, and join a worldwide community of individuals and institutions working toward a 100% renewable energy future. If you are a researcher, industry professional, student, or organization looking for a credible solar energy hub rather than a product vendor, ises.org is the site to check.

What the organization is

The homepage positions ISES around a single clear goal: driving the transition to a 100% renewable energy future. The organization frames itself as an international society, not a commercial platform, and its public identity centers on advocacy, knowledge sharing, and convening people across countries and sectors.

Two things follow from that positioning:

• It is membership-based. The site invites individuals and organizations to "Join Our Global Solar Community," and it maintains a dedicated section for Corporate and Institution Members as well as Partners.
• It is research- and policy-oriented. The content mix leans toward publications, conference planning, and commentary on the energy transition rather than consumer products or installation services.

What you will find on the site

The site organizes its public content into a few recurring streams. Based on the homepage, these include:

A few observations from the homepage content are worth noting for anyone deciding whether to rely on the site:

• The journal is a core asset. Multiple Solar Energy volume announcements appear in the latest news feed, which suggests the journal is one of the society's main ongoing outputs.
• The pv magazine column is a regular channel. The columns are dated monthly (August, September, and October 2026 on the homepage), so readers can expect recurring commentary rather than one-off posts.
• Conference planning is active. EuroSun 2026 is promoted, and the EuroSun 2028 expression-of-interest process is reported as closed, indicating a multi-year event cycle run with partners such as the IEA Solar Heating and Cooling Programme.

Who it is for

The site's framing points to several distinct audiences:

• Researchers and academics who want journal content and conference participation.
• Industry and institutions interested in corporate or institutional membership and partner visibility.
• Students and early-career professionals looking for a global community and event access.
• Policymakers and commentators following the society's positions on electrification, storage, and solar deployment.

If your goal is to buy solar panels, compare installers, or get a quote, ises.org is not built for that. It is a knowledge and community hub.

How to use the site

1. Start with Latest News to see current publications, columns, and event updates. This is the fastest way to understand what the society is actively working on.
2. Check the Publications and journal listings if you need solar energy research. The Solar Energy journal volumes are announced as they are released.
3. Review the Events section for conferences such as EuroSun and for webinar announcements.
4. Look at membership options if you want to join the community. The site distinguishes individual membership from Corporate and Institution Members and Partners.
5. Use the login area if you are already a member; the homepage includes a User login entry point.

A practical note: the homepage shows a search function, so if you are looking for a specific topic, journal issue, or past column, searching is likely faster than browsing the news feed.

What to keep in mind

• Membership terms and pricing are not stated on the homepage. The site invites you to become a member but does not display costs or detailed benefits in the material available, so check the membership pages directly before committing.
• Some content sits behind a login. The presence of a user login suggests member-only areas, though the homepage does not specify what is restricted.
• Dates on the site run into 2026. The news items are dated August through October 2026, so treat the feed as a current snapshot rather than an archive of past years.
• The society is broad, not niche. Its scope spans research, policy commentary, storage, electrification, and regional deployment, so expect a wide range of topics rather than deep coverage of one technology.

In short, ises.org is the online home of the International Solar Energy Society: a membership organization and publishing hub for the global solar and renewable energy community. It is most useful if you want research, event access, or community membership, and least useful if you are shopping for solar products or services.

ISES (ises.org) covers renewable energy through three main channels: a news column published in pv magazine, its peer-reviewed journal Solar Energy, and conference material tied to events such as EuroSun. The topics visible on its site cluster around electrification and demand growth, rooftop solar in developing markets, long-duration storage and grid flexibility, and solar research published in the journal. If you want to know what the organization actually writes about before joining or following it, the news column and journal volumes are the most direct evidence.

The main topic areas visible on the site

Electrification and rising electricity demand

The October 2026 ISES column in pv magazine, titled "Electrifying everything," frames the issue around COP31's aim to raise electricity's share of global final energy demand from 20% to 35% by 2035. This is the macro-level theme: how much of total energy use shifts to electricity, and what that means for accelerating a clean, affordable transition. Readers interested in demand-side trends and international targets will find this the most policy-oriented strand of ISES coverage.

Rooftop solar in African markets

A September 2026 column, "Very low cost rooftop solar slashes domestic energy cost – Part 3: African Countries," looks at the 54 countries of the African continent. The site's summary notes that rooftop photovoltaics is growing rapidly in some African nations but that uptake is highly uneven. This is a recurring pattern in ISES coverage: a specific technology (rooftop PV), a specific cost claim (very low cost reducing domestic energy costs), and a regional focus that highlights disparity rather than a single continental trend.

Long-duration storage and grid flexibility

An August 2026 column covers "Unlimited long duration, long-lived pumped hydro storage." The framing is that solar- and wind-dominated grids need abundant long-duration storage, and that off-river pumped hydro offers large potential — the summary cites 800,000 sites. This topic connects the generation side (variable renewables) to the storage and flexibility needed to absorb it.

Peer-reviewed solar research

The site lists Solar Energy journal volumes as they are published, for example Volume 315 Parts 1 and 2 and Volume 314 Parts 1 and 2 across August 2026. These entries point readers to the latest solar energy research rather than summarizing findings on the homepage, so the journal is the place to go for technical depth.

How the channels differ

What this means if you are deciding whether to follow ISES

The site positions ISES as "the global voice for renewable energy" and frames its mission as driving a transition to a 100% renewable energy future. Its public content is a mix of short, argument-driven columns and pointers to journal research, with conference activity layered on top. If your interest is in electrification policy, solar deployment in emerging markets, or storage for high-renewable grids, the column archive is the fastest way to sample the coverage. If you need citable research, go directly to the Solar Energy journal listings. Note that some material sits behind a user login, and the site does not publish pricing details on the pages reviewed here, so check membership terms directly before assuming what access a given tier includes.

ISES (the International Solar Energy Society) organizes the EuroSun conference series and co-plans it with the IEA Solar Heating and Cooling Programme. The ises.org site currently shows EuroSun 2026 as an upcoming event and reports that planning for EuroSun2028 is underway, with the call for expressions of interest for hosting it now closed. Around these conferences, ISES also runs webinars and publishes research and news through the Solar Energy journal and a regular column in pv magazine.

The EuroSun conference series

EuroSun is the event most clearly tied to ISES on the site. Two editions appear in the current listings:

The EuroSun2028 notice is useful if you are tracking where the conference will be held: the host-selection stage has already passed, so the next public information will be the announcement of the selected host and venue rather than a new call.

How the EuroSun hosting process works

The EuroSun2028 notice illustrates the pattern:

1. Call for expressions of interest — institutions signal interest in hosting.
2. Review — ISES and the IEA Solar Heating and Cooling Programme assess the submissions (the site reports 5 were received).
3. Selection and announcement — the host is chosen and details are published.

If you represent an institution interested in a future edition, the practical step is to watch the ISES news feed for the next call rather than contact the site about EuroSun2028, whose call is closed.

Other events and activities listed on ises.org

Beyond EuroSun, the site's navigation and news feed point to several recurring activities:

• Webinars — listed as a standalone section in the site navigation.
• Solar Energy journal — ISES presents research from the journal, with volumes and parts announced in the news feed (for example, Volume 315, Parts 1 and 2, and Volume 314, Parts 1 and 2).
• ISES column in pv magazine — a monthly column; recent topics include electrifying everything and COP31 targets, very low-cost rooftop solar in African countries, and off-river pumped hydro storage.
• Blog posts and latest news — short updates on publications and society activities.

How to find current event details

The site's news feed is the most reliable place to confirm dates and locations, because the excerpts available here do not include venue or registration details for EuroSun 2026. To check:

1. Open ises.org and go to the Latest News section.
2. Look for posts tagged to EuroSun or the events section.
3. For member-only material, use the User login link in the site header.

Note that the site shows a login option but the available material does not state whether event pages, proceedings, or webinar recordings require membership. Treat access as something to verify after logging in rather than assuming it is open or restricted.

Choosing what to follow

• If you want to attend a conference: track EuroSun 2026 announcements on the news feed; venue and registration information is not in the current excerpts.
• If you want to host a future EuroSun: wait for the next call for expressions of interest, since the EuroSun2028 round is closed.
• If you want research rather than events: the Solar Energy journal announcements and the pv magazine column are the regular outputs.
• If you want ongoing updates between conferences: the webinar section and blog posts are the recurring channels.
