Apollo is the theme to buy if you install or sell solar. It is the only one of these eight written for a solar company rather than adapted from a general green-business layout, it runs on Elementor, and a single-site licence is $59. If solar is one service among several, Provem is the better shape. Prices checked September 2026.
Five of the eight run on Elementor at $59 a site. The three at $51 are built on older frameworks, and on a site you expect to keep for years that matters more than the $8 you save. Each entry below says which stack it uses.
Best Solar WordPress Themes
#1. Apollo
Apollo is a solar energy company theme from ZEMEZ, and its demo content is the closest thing here to a working installer’s site. Home, Services, Projects, Blog and Contacts all come pre-built, with counter widgets for figures like panels fitted or tonnes of carbon saved, a team section and Google Maps. It suits an installer or panel supplier who wants something credible live in a weekend and will keep editing it in Elementor afterwards. WPML, MailChimp and Ecwid are supported, so a small parts shop is possible later without changing theme.
Personal licence $59, commercial $86, with six months of author support.

#2. Provem
Provem is the pick when solar sits alongside other work. ZEMEZ aims it at renewable power, utilities, gas and oil, industrial and civil engineering, so the layout gives equal weight to services, projects and credibility blocks instead of pushing one product. Both the header and the footer are editable in Elementor, which is less common at this price than you would hope, and testimonial sliders, counters, accordion FAQ blocks and Google Maps are built in.
Personal licence $59, commercial $86. The vendor lists support for WordPress 5.6 through 6.9 and PHP 7.4 through 8.4, which is the widest compatibility range on this page.

#3. EMpower
EMpower is aimed at solar farms and larger renewable power operators, and it is the only theme here that ships with WooCommerce integration, so panels, inverters or a monitoring subscription can be sold from the same site. Green-and-white palette, animated sections, full demo content, and a layout that works as well for a single landing page as for a corporate site. One caveat: the vendor lists compatibility up to WordPress 6.4, so check it against your install before you commit.
Personal licence $59, commercial $86, with six months of author support.

#4. Ecotech
Ecotech reaches past solar into environmental services and green technology generally, and it is the most configurable theme on this list: seven header styles, three footers, several blog layouts and dozens of pre-built pages, plus pricing tables, calls to action, sliders and testimonials. Choose it if you expect the site to grow past a dozen pages and you would rather those options came with the theme than with five more plugins.
Personal licence $59, commercial $86. The product page records 244 sales and 17 reviews, so there is a real user base behind it.

#5. Epa Green
Epa Green reads like a campaigning site rather than a sales site, which makes it the right shape for a community energy co-op, a trust or an environmental charity that happens to talk about solar. It is also the most actively maintained theme here: ZEMEZ last updated it in June 2026 for WordPress 7.0. Google Maps, tabs, dropdown menus and a performance panel come as standard, and the demo pages arrive configured rather than blank.
Personal licence $59, commercial $86.

#6. Eco Life
Eco Life is the cheapest route onto this list at $51, and it looks right for an ecology or green technology firm: background video on the hero, sliders, and a live customiser for logo, colours and typography. The catch is underneath. It runs on Cherry Framework 5, and buyer reviews on the product page report trouble on PHP 8 and recent WordPress releases. Only worth it if you know your host and your plugins are content on PHP 7.
$51 with a GPL licence and six months of support.

#7. Helilar
Helilar is RockThemes’ renewable energy theme, with parallax scrolling, a sample-data installer, Bootstrap 4 underneath and WPML support for a second language. It builds pages in RockThemes’ own Power Page Builder rather than Elementor, so nothing you learn here transfers if you change theme later. That is the trade for the lower price, and it is a real one.
$51 with a GPL licence and six months of support.

#8. EcoPower
EcoPower targets green tech, alternative power and recycling firms, and its Cherry Services plugin gives the tidiest services block of the three cheaper themes, with an image, text and a video for each service. WPML, MailChimp and Ecwid are supported too. Same warning as Eco Life, though: Cherry Framework 5 is an older stack than Elementor, and you are betting on RockThemes keeping it current.
$51 with a GPL licence.

Which solar theme should you pick?
Buy Apollo if you install or sell solar and want the shortest path to a credible site. Buy Provem if solar is one line of business among several. Buy Epa Green if you are a co-op, a trust or a charity rather than a contractor. The three $51 themes only make sense if the budget genuinely will not stretch, and even then check your PHP version first, because an older framework on a modern host is the quickest way to a site that will not load.
If raw speed matters more to you than a solar-specific demo,
our lightweight themes roundup is a better starting point than any of these. Working in a neighbouring trade?
