Stop depending on a grid you don't control. Our free planning tool helps Costa Rica homeowners understand their energy usage, size a solar system, and take the first real step toward independence.
We believe the information should come first. That's why the planner is completely free. Understand your home, size your system, make your decision — on your own terms. That's the whole idea.
Costa Rica runs on over 99% renewable electricity at the grid level — yet homeowners still overpay, face outages, and have no clear path to self-sufficiency. We're here to change that. One home at a time.
The barriers to solar in Costa Rica aren't technical. They're informational. We fix that.
Tarifa 2 rates stack against high consumers. Large family homes — especially those running multiple A/C units — regularly see ₡150,000 to ₡250,000 monthly with no visibility into what's driving it.
Tropical storms, maintenance windows, falling trees. When the grid goes down, you go dark. A solar and battery system means you stay on — regardless of what happens outside your property.
Installers ask for a site visit. Weeks pass. You still don't know if you need 8 panels or 20. pureCASA.solar gives you the numbers — clearly, honestly — before you talk to anyone.
No engineering knowledge required. Just your appliances and a few minutes. We handle the math.
Add your fridge, A/C, washing machine, lights — anything that draws power. Use our quick-add library of 40+ common appliances or enter custom specs. We calculate real Wh/day for each one.
Based on your total energy usage and Costa Rica's regional peak sun hours, we calculate exactly how many panels, how much battery storage, and what inverter capacity your home needs.
Export a professional PDF or Excel report with all your data. Share it with any installer to get accurate, comparable quotes — or keep it for your own planning and records.
Most solar planning starts with your current energy usage — then sizes a system around it. We think differently. Reduce your load first, and you need fewer panels, smaller batteries, and a smaller inverter. That means a lower upfront cost and a system that works harder for longer.
In Costa Rica, air conditioning is the single biggest driver of high ICE bills — especially in homes with multiple units running through the night. The good news: modern inverter A/C technology uses 60–70% less electricity than standard units. Swapping your appliances before going solar is often the highest-return move you can make.
A standard 12,000 BTU A/C draws ~1,200W. A high-efficiency inverter unit doing the same job draws ~350–450W. Run it 8 hours/day and that's a difference of ~5 kWh per day — per unit.
Replacing two standard A/C units with inverter models can reduce your daily load enough to eliminate 4–6 solar panels from your system design. That saving alone often covers the cost of the upgrade.
Inverter compressors modulate speed instead of cycling on/off. They maintain temperature with a fraction of the energy — and they're quieter, last longer, and dehumidify more effectively in CR's climate.
Standard electric dryers are among the most wasteful appliances in any home — 4,500–5,000W for an hour of use. Heat pump dryers recycle hot air internally, using around 800–1,000W for the same load.
The ducha eléctrica (electric shower head) is ubiquitous in Costa Rica — and draws 4,000–6,000W every time it runs. A heat pump water heater replaces constant on-demand heating with a 50-gallon tank using ~500W.
Airbnb guests leave A/C running 24/7 with no consideration for the bill. Smart controllers let you set schedules, temperature limits, and auto-off timers remotely — protecting your system and your guests' comfort.

We only recommend equipment that holds up in Costa Rica — humidity, heat, voltage fluctuations and all. No paid placements. Just what works.
A serious power station for real home loads. 2,048Wh base capacity, expandable to 8,192Wh. Handles a ducha eléctrica, refrigerator, and lighting through a full night outage.
Fast charging (0–80% in 50 min), smart app control, and modular expansion. The go-to for homeowners who want plug-and-play simplicity with serious power capacity.
Rack-mount lithium battery systems purpose-built for solar storage. Rugged, modular, and competitively priced — a strong choice for homeowners scaling up from a starter system to whole-home backup.
The choice of serious off-grid installers across Latin America. Inverter and charger in one unit, designed for 24/7 reliability in tropical climates. Built to last decades.
"Our team came to Costa Rica and never left — it's home now. We brought experience from the energy industry, including years working on solar solutions in remote areas where the grid simply couldn't reach. We saw firsthand what energy independence looks like when it works. pureCASA.solar is the business we wanted to exist when we were trying to figure this out for ourselves."
pureCASA.solar was founded by people who chose Costa Rica — and chose to make it their forever home. We brought real-world energy experience with us, including time spent deploying solar in remote locations where no grid existed. We know what works, and what doesn't.
Costa Rica is one of the greenest countries on earth. Its people deserve the tools to harness that energy for themselves — not just for the grid, but for their own homes, their own independence, their own future.
The planner is free. The information is honest. The mission is real.
