TL;DR: Peru’s solar proposal requirements differ from most Latin American markets: SEIN interconnection compliance, OSINERGMIN tariff structures, generacion distribuida regulations under Decreto Legislativo 1221, and USD-denominated project economics. SurgePV delivers all-in-one design, simulation, and proposal generation with self-consumption modeling at $1,899/year for 3 users. PVsyst remains the bankable simulation standard for utility-scale projects. Aurora Solar offers polished proposals but lacks Peru-specific regulatory features.
Peru’s solar market is accelerating fast.
The country added 454 MW of utility-scale solar in 2025, bringing total installed PV capacity past 950 MW. Projections from COES (Comite de Operacion Economica del Sistema Interconectado Nacional) estimate photovoltaic capacity will reach 2,362 MW by the end of 2026. The southern regions of Arequipa, Moquegua, and Tacna receive 6.5-7.0 kWh/m2/day of solar irradiance, among the highest levels on the planet.
But the distributed generation segment — residential and commercial rooftop solar — is where proposal software matters most. Decreto Legislativo 1221 established the legal framework for generacion distribuida, allowing electricity users to generate power for self-consumption and inject surpluses into the distribution network. OSINERGMIN sets the tariffs. Distribution companies verify technical compliance. And COES manages energy injection into the SEIN.
Most solar proposal software platforms were built for the US residential market. They calculate savings using US utility rate structures, generate proposals in English, and model net metering policies that do not exist in Peru. The result: Peruvian EPCs spend hours adapting proposals in spreadsheets, manually calculating self-consumption ratios, and producing documentation that does not meet local standards.
The right solar software platform handles SEIN interconnection modeling, self-consumption analysis with surplus injection, OSINERGMIN-compliant documentation, and USD pricing — without workarounds.

Real-World Example
A commercial EPC in Lima handling both residential and C&I projects was paying over $8,000/year for separate design, simulation, CAD, and proposal tools — and spending 10 hours per week on data re-entry between platforms. After consolidating to SurgePV at $4,497/year (3-user plan), they cut software costs by 44% and freed up nearly two full working days per week.
You might be wondering: if SurgePV does all this, why haven’t I heard of it? Fair question. PVsyst has had a 30-year head start. Aurora Solar has spent hundreds of millions on marketing. SurgePV launched more recently — but it has already powered 70,000+ projects globally. The platform was built specifically for the workflow gaps that legacy tools leave open, especially automated electrical engineering, which no other platform offers natively.

Why Peru’s Solar Market Demands Better Proposal Tools
The generacion distribuida opportunity
Decreto Legislativo 1221 opened Peru’s distributed generation market by allowing electricity users to generate power for self-consumption and inject surpluses into the distribution network. The regulation established the legal framework, but the technical requirements — SEIN interconnection compliance, OSINERGMIN tariff calculations, and distribution company approvals — create documentation demands that most global solar software platforms were not built to handle.
Self-consumption economics drive the business case
Unlike markets with generous feed-in tariffs, Peru’s distributed generation model is built around self-consumption. The financial case for rooftop solar depends on how much generated energy is consumed on-site at retail tariff rates versus how much is injected into the grid at lower wholesale rates. Accurate self-consumption modeling is not optional — it is the entire proposal.
Your software needs to model hourly load profiles against hourly generation profiles, calculate self-consumption ratios for specific buildings, and present the financial impact in USD with Peruvian energy price escalation assumptions.
SEIN interconnection documentation
Connecting a solar system to Peru’s SEIN requires technical documentation that distribution companies (Luz del Sur, Enel Distribucion, SEAL Arequipa) review before granting approval. This includes system specifications, electrical diagrams, protection device details, and generation capacity declarations. Your proposal software should generate this documentation automatically — or you will spend hours producing it manually for each project.
USD-denominated project economics
Peru’s solar equipment market operates primarily in USD. Modules, inverters, and mounting systems are priced in dollars. But electricity tariffs are set by OSINERGMIN in Peruvian Soles. Proposal software for Peru needs to handle dual-currency economics: USD for system costs and equipment, Soles for energy savings calculations, with exchange rate sensitivity analysis for long-term financial projections.

When You May Not Need Advanced Proposal Software
Not every solar project in Peru requires comprehensive proposal platforms. Consider simpler alternatives if:
- Small residential projects with standard layouts — Basic design tools or manufacturer calculators may suffice for simple rooftop arrays under 3 kW.
- Engineering is outsourced — If your company uses an external engineering firm, you may only need proposal and CRM tools.
- Very limited project volume — Teams handling fewer than 5 projects per year may find manual workflows more cost-effective than annual software subscriptions.
- Non-technical sales teams — Sales-focused companies without in-house engineers may only require proposal generation tools.
Most Peruvian EPCs, developers, and medium-to-large installers benefit from integrated platforms that reduce manual work and improve accuracy. With SEIN interconnection requirements, OSINERGMIN compliance, and self-consumption modeling complexity, manual workflows create bottlenecks that delay project approvals and cost sales.
Bottom Line
For Peruvian EPCs and installers, SurgePV delivers the most complete design-to-proposal workflow with automated SLD generation, bankable P50/P90 simulations, and integrated Spanish-language proposals — all at $1,899/year for 3 users. Book a demo to see it in action.
