☀️ Peak sun hours in Peru
Egypt gets outstanding sun — roughly 5.5 to 6.5 peak sun hours. Upper Egypt and the desert are highest; the Delta and north coast a little lower.
| Region | Approx. peak sun hours (annual avg) |
|---|---|
| Southern coast (Arequipa & Moquegua) | ~5.8 – 6.3 |
| Central coast (Lima) | ~4.3 – 4.8 |
| Highlands (Cusco) | ~5.0 – 5.5 |
| North coast (Trujillo) | ~5.0 – 5.4 |

⚡ Electricity prices in Peru
Residential electricity runs roughly PEN 0.70–0.95 per kWh depending on your distribution zone — mid-to-high for Latin America, and the grid tariff keeps climbing.
💸 Incentives & net metering
Peru's net billing scheme (Ley 31090) lets residential and commercial systems export surplus at regulated prices against future bills. Generation units under 20 MW connect under the simplified distributed-generation regime — confirm connection requirements with your distribution company.
💰 System cost & payback in Peru
Local installation is relatively affordable; payback keeps improving:
| System size | Approx. cost | Suits |
|---|---|---|
| 3 kW | ~PEN 10,000 – 14,000 | Small home |
| 5 kW | ~PEN 16,000 – 22,000 | Typical family home |
| 10 kW | ~PEN 30,000 – 42,000 | Large home / small business |
Work out your own numbers with the ROI calculator and the bill savings calculator, or design the whole system with the system report builder.
💡 Local insight: Peru
The coastal fog (garúa) is the local wildcard: Lima sees gray skies for months in winter yet the solar resource still averages 4.3–4.8 peak hours — most of the energy arrives in the clear midday window. Owners who size for that window and shift loads to it do far better than those who just compare nameplate ratings. In Arequipa the desert sun is world-class but dust storms pit glass; cleaned or coated modules keep output honest.
