What happens if I don't include the Top50-Solar logo?

If you do not include the logo and have not selected the corporate  membership, then your entry will be de-activated on the Top50 site and you will no longer appear in Top50-Solar. To fix this, login to your account to select your HTML-code and insert into your pages.  

If you attempt to modify the logo in any way your entry will be deleted.  

If you have any queries regarding this please contact us.


fold faq

What happens if I accidentally delete the logo, can I get it back?

Yes you can!   Simply login to your account and click show HTML option.

Please ensure you always insert the logo otherwise you will find your listing will become deactivated unless you have requested the corporate (chargeable) option not to display the logo.


fold faq

How can I test if my logo has been correctly placed on my web site?

You should check the following:

is the logo visible in the chosen place on your homepage?

can you find the source code (identical to that in your email) in your HTML page?

To view it open up your page in a browser, in Firefox click CTRL-F and search for “Top50”. In Internet explorer go to page, show source code and then search using CTRL-F for “Top50” 

fold faq

Can I register with as many toplists as possible?

You might think that the more toplists you register with the better. However our experience from Top50-Solar members who have tried this in the past is that there is no benefit in adding additional toplists.  In fact if anything it can have a negative effect. Cluttering your pages with lots of logos appears unprofessional and impacts your design. Make use of our distinctive logo which is used throughout the industry. You will soon see that this approach pays off!

Types of membership

There are two types of membership; Standard  - which is completely free and Corporate which incurs an additional annual charge. Both types enjoy the same benefits and features.  Corporate membership suits those companies who do not wish to display the Top50-Solar logo on their homepage.   In that case a charge applies.  

Standard Membership:
The default standard membership is free and includes all the benefits of Top50-Solar. Your company will be listed in the toplist and in the corporate directory and the content of your pages will be scanned with solar search.  You will also get your own detailed, search engine optimised company page with a detailed description (up to 5000 words). Twitter messages, videos and more can be displayed. As long as you insert the Top50-Solar logo on your site, this service is offered absolutely free of charge. Click for standard registration  

Corporate Option:
Some Companies for whatever reason, may not wish to display the Top50-Solar logo.  In this case we offer you a corporate option for an annual charge. If you are interested in this option we would be happy to help.  Contact us to discuss pricing options.

How do I make the Top50-Solar logo visible on my page?


When you first register, the HTML code is included on the registration email that was sent to you. Simply cut and paste this code into your homepage wherever you wish the logo to appear.

If you are unfamiliar with HTML the following instructions on incorporating an HTML code into websites may be of help. Please be aware that this information refers to a Google product and has absolutely nothing to do with Top50-Solar membership. However they may be useful as a guide.


Toplist FAQs

Show all / Hide all

fold faq

What is the Top50-Solar toplist?


Top50-Solar is a global web directory of solar and renewable energy websites listed in order of popularity - measured by user traffic.  Sorting companies in this way allows you to target the most popular websites first.  

fold faq

Why is there a Toplist and a Company Directory?


We offer both searches purely for your convenience!

The Toplist sorts companies in descending order of popularity (measured by user traffic) while the Company Directory A-Z sorts companies alphabetically.

Both listings allow you to narrow your search using country, company name, city and keyword searches 




fold faq

What is the "Map View“?


This is a geographical view of the companies listed in the Toplist.  

This is very handy if you are on a single country for a visual view all the companies listed and their location.

Note: we do not recommend you use this view when "All countries" are selected.



fold faq

How do I use the search?“


Search by Keyword, company name or city or a combination of these.

For example, to search for all installers in Poole United Kingdom:

  • select United Kingdom in the country drop down
  • type installer in the key word tab
  • enter Poole in city tab


All installers in or close to Poole will then be visible.

Use the x to clear and start a new search








fold faq

What is the “Tags” feature?


All registered companies can apply specialist tags - such as Photovoltaic  - in their listing. This function enables visitors to use keywords to narrow down their company search.

fold faq

How can I add my company/homepage to the Toplist?


Simply register your company details. You can add a short and long description of your company, banner and logo, plus twitter and facebook links. 

Once you have entered all the required details you will be sent a confirmation email which also contains the HTML code for our logo.

Insert the logo exactly as it is provided, into your web pages.  

Entry into our directory is free of charge as long as you display the logo.  If you do not wish to show it then we also offer a chargeable corporate option
