Solar and battery guides
Solar system prices in Costa Rica: costs & savings
A useful solar quote starts with your electricity use, roof and backup priorities. Panel count alone does not tell you what the installed system will cost or how much it will save.
How much does a home solar or backup system cost?
Think of it like buying a car. A compact car and a fully equipped SUV are both cars, but the price depends on size, features and how you plan to use it. A home energy system works the same way.
As a rough guide, the equipment for a simple automatic battery backup starts at around US$6,000. The equipment for a full solar installation with large battery storage for a bigger home can reach around US$80,000. Most homes fall somewhere in between, depending on how much electricity you use, which appliances must keep running during an outage and whether you want solar now or later.
These figures cover equipment only. Labour, installation materials and any additional work come on top, and they depend on the installation: roof access, cable runs, trenching and electrical upgrades all change the total.
Equipment only. Labour, installation materials and any additional work are extra and depend on the installation. Sizes and figures are indicative; your proposal follows a property assessment. Backup hours assume about 80% of battery capacity is usable and no solar recharging; production assumes about 4.5 peak sun hours.
What changes the installed price?
The main factors are solar capacity, inverter power, battery capacity and installation work. Roof condition, shading, cable routes and changes to the electrical installation also affect the proposal.
Equipment prices can change daily, and every installation has different requirements. After discussing your property, we prepare an estimated range for your home covering equipment, installation materials and labour.
All three cost groups are estimates at this stage. We explain the assumptions, allowances and any work still to be assessed. A site assessment and agreed scope are needed to confirm a quotation; an initial range is not a fixed package price.
Labour is part of the installation budget, alongside equipment and materials. It covers the agreed installation work, configuration, testing and commissioning. Roof access, cable routes, trenching and electrical upgrades can change the scope.
Suntiago provides property-specific quotes rather than fixed packages. Compare proposals by what is included: equipment, installation, selected backup circuits, commissioning, warranty terms and support.
Use your ICE bills to estimate savings
Several recent bills help establish consumption in kWh and seasonal changes. We also ask when you use electricity: daytime demand can use solar directly, while evening demand may need stored energy.
Our systems use solar in the home and store available energy in batteries; they are not designed to sell electricity to ICE. Savings depend on production, consumption, tariffs and system settings.
A real example from Santiago
Our Santiago residential project combines 6.6 kWp of solar panels, a 12 kW inverter and a 10 kWh battery. The homeowner reported monthly ICE bills falling from approximately US$400 to US$100: a difference of about US$300, or 75%.
Those are customer-reported bills for one home, not a guaranteed result. If that monthly difference stayed constant, it would equal about US$3,600 per year. Weather, occupancy and electricity use can change the outcome.
One Santiago project: approximately 75% lower reported bills. Results vary; this is not a forecast for your home.
How should you assess payback?
A simple starting point is installed cost divided by estimated annual savings. A fuller comparison also accounts for maintenance, equipment replacement, financing and changing electricity costs. Backup during outages has value, but it is separate from bill savings.
Before choosing a size, decide whether your priority is a lower bill, outage protection or both. We use that decision and a site assessment to prepare your proposal.
