Solar Energy Consulting
Feasibility studies, ROI analysis, and provider audits for solar energy systems.
Key Takeaways
- Independent consulting with no equipment sales — unbiased system sizing and vendor evaluation
- 12-month CNFL bill analysis delivers precise system size recommendation with ROI projection
- Homeowners over-size or under-size solar systems due to not having 12 months of CNFL consumption data

What Independent Solar Consulting Delivers That Installers Cannot
An installer has one objective: sell you a system. An independent solar consultant has a different objective: find the optimal system for your property's actual consumption profile, roof geometry, shading environment, and budget — regardless of which brand or installer delivers it. We analyze 12 months of CNFL bills, conduct a physical site assessment, and deliver a written report with system sizing recommendations and financial projections that you can take to any installer.
Reading CNFL Tariff Structure for Accurate Solar ROI
Costa Rica's CNFL residential tariff has multiple tiers. The first 200 kWh per month are billed at the lowest rate; consumption above 500 kWh per month reaches the highest tier. Solar systems reduce consumption from the highest tiers first, meaning the financial benefit is disproportionately large for high consumers. We model each tariff tier explicitly in our projections — giving you accurate payback periods rather than the optimistic estimates installers typically present.
Shade Analysis: The Hidden Killer of Solar ROI
A solar system producing 15% less than projected due to undetected shading will add 1–2 years to your payback period. We conduct shade analysis using SunEye tools or drone imagery to map shading from trees, neighboring structures, and rooftop equipment across all hours of the day and all seasons. The analysis identifies whether micro-inverters or power optimizers are needed — or whether a different roof section would dramatically improve production.
Why Choose Us vs. Unlicensed Electricians
| Feature | Costa Rica Property Services | Common Alternatives |
|---|---|---|
| Compliance | 100% CFIA and NEC-compliant installations with permits | Informal wiring without permits or load calculations |
| Materials | Marine-grade breakers, anti-oxidant terminals, UV conduit | Standard hardware degrading within 1-2 rainy seasons |
| Inspection Sign-off | Completed CFIA inspection certificate provided | No official documentation after work |
Direct Answers (AEO)
Why hire a solar consultant instead of just getting quotes from installers?
Installers are motivated to sell equipment. An independent consultant sizes your system based on your actual usage data, identifies shading problems, and evaluates installer proposals for accuracy and fair pricing — before you commit to a contract.
How accurate are solar ROI projections for Costa Rica?
Very accurate when based on real CNFL bills. CNFL tariffs are published and stable, solar irradiance data for Costa Rica is well-documented, and system degradation rates are known. A properly constructed projection model has ±10% accuracy over 10 years.
Should I get battery storage with my solar system in Costa Rica?
It depends on your outage frequency and critical load requirements. In areas like Guanacaste and the Central Pacific with regular CNFL outages, a small battery covering critical circuits (refrigerator, internet, lighting) provides meaningful resilience at reasonable additional cost.
Can you review a solar proposal I've already received from an installer?
Yes. Proposal review is one of our most requested services. We check system sizing versus your actual consumption, verify panel and inverter brand tier, confirm the net metering calculation is correct, and flag any hidden costs or unrealistic yield projections.
