Solar power in Las Terrenas: panels, batteries & installation
The Las Terrenas sun costs nothing and shines almost all year. We help you use it to ride out power cuts and produce part of your own electricity.
Sunlight is free; the installation is not. That is why we start with an indicative estimate and a site visit before any quote.

Frequently asked questions
See allWho does the installation?
Installations are carried out by THERD SRL or by selected partner installers; the quote always states who does the work. That way you know, before signing, who will be working at your property and who is responsible for the installation. If you are an installer or supplier in the area and would like to work with us, visit the installers and suppliers page.
How much does a solar installation cost?
The price is set on quote, after the technical visit. It depends on your consumption, your goal (backup, savings or autonomy), the amount of battery storage, the type of roof, access and the equipment chosen. That is why we do not publish any price until it has been validated for your specific case: a generic price would be misleading. The solar calculator gives you a first indicative estimate to help you get your bearings, but it is not a quote. The detailed quote is provided in writing after the visit.
Does my request commit me to anything?
No. Sending a request or using the calculator costs nothing and commits you to nothing. A request is not a quote: it is the starting point for us to contact you on WhatsApp and understand your needs. The quote comes after the technical visit, in writing, with details of the equipment and the work. Only you decide whether to accept it. If you change your mind at any point, just tell us on WhatsApp.
Do I need a technical visit?
Yes, to receive a detailed quote. Every home is different: roof orientation and condition, shade, electrical panel, space for batteries, actual consumption. The visit lets us check all of this on site and size the system with real data instead of assumptions. The terms of the technical visit are explained when we contact you on WhatsApp, before an appointment is set. In the meantime, the calculator gives you a first indicative estimate.
Do solar panels work during a power outage?
It depends on the system. A grid-tied system without batteries generally shuts down during an outage: for safety, the inverter stops so that it does not send power into the grid while technicians are working on it. With a hybrid or off-grid system with batteries, yes: the house stays powered within the limits of the battery capacity and the inverter's power, and the panels recharge the batteries during the day. You usually choose the priority circuits that stay backed up.
