Who it's for

Websites for energy and HVAC contractors

Give customers the evidence and technical details to compare suppliers.

Solar PV and batteries

Project references, output and savings data, subsidy information. The website proves the quality of your work.

PV installations · Batteries · Virtual battery · Wallbox · Solar water heating

Heat pumps and heating

Customers look for a turnkey expert, calculation, installation, service. A website with case studies wins those who choose by competence.

Air-to-water · Ground-to-water · Hybrid systems · HP service · Heating works

HVAC and ventilation

Heat recovery units, HVAC for new builds and retrofits, AC. A website sets you apart from competitors who only have a Facebook page.

Heat recovery · HVAC · Air conditioning · Residential ventilation · Industrial HVAC

When to discuss a larger project: Binding-price configurators, customer portals with installation monitoring and stock-system integrations require a separate application scope.

How much a website costs by scope is covered on the page how much a website costs.

FAQ

Answers to what we hear most often

If you don't find your question here, reach out, we'll gladly answer it in a free consultation.

Can I have a PV or heat pump ROI calculator on my site?

Yes, in the Business and Premium packages a simple calculator is included in the price and gives the customer an estimate of cost, savings and payback. The calculator also collects enquiries: the visitor fills in their details and you call with a prepared offer.

Will the website help with subsidy information?

Absolutely. For solar PV and heat pump companies a section on Czech subsidies (NZÚ, Modernisation Fund, OPŽP) is essential, the client arrives informed and decides faster. These pages also bring people from Google who search for "nzú fotovoltaika" or "heat pump subsidy".

Will the website be optimised for local search?

We connect the site to Google Maps and your Google Business Profile and set it up so Google shows you to people nearby, for example for "solar PV Brno" or "heat pump installation Prague".

Do I have to pay everything at once, or can I pay in parts?

You pay in two parts. Half of the price as a deposit once the contract is signed, the other half only after you approve the finished website.

What's included and how much will the website cost me per year to run?

The price includes the full website, domain and hosting for the first year, SSL, basic SEO, contact form and Google Analytics. From the second year you pay for running the site, hosting and domain together, typically about EUR 40 a year, invoiced once a year. No monthly fee for the CMS or for maintenance, you order changes only when you want them.

Who owns the website and the domain, and what if we part ways?

You do. The domain is registered in your name or your company's name from the start, once the invoice is paid you get access to everything including the source code. If we part ways, you can move the website to another host or developer at any time with no penalties, we hand over the complete code, the database and all credentials.

Do we sign a contract and will I get an invoice?

Yes, a contract for work covering the scope of the website, the price and the delivery date. We send it to you already signed on our side and you simply reply from your e-mail that you agree, nothing gets printed. We're VAT-registered, so you can expense the invoice.

What if I don't have any copy or photos?

We write the copy from the information you give us, you supply the photos, and we quote a photo shoot or stock photos upfront.

Who builds the website and how do we start?

We are the developers ourselves, since 2017 we have completed 119 projects, browse our work at devboys.cz/en/references. Call +420 601 386 720, write to info@devboys.cz or fill in the form at the bottom of the page. You are answered by the developer who will build the site, and after a free, no-obligation 30-minute consultation you know the exact price and delivery date.
