Request a solar EPC proposal in Chile

Start with the sizing tool

The calculator below produces a reference figure in a few steps: draw the available roof or ground area, or enter your monthly bill, and it returns an indicative capacity and investment. It is a starting point, not the proposal — a real project is sized on the measured load curve.

Note: the calculator interface is in Spanish, and all amounts are Chilean pesos (CLP), not US dollars. If you would rather skip it, the contact details are at the foot of this page.

What the proposal contains

Six things, all of them in writing. We do not issue a headline price without the engineering behind it.

• Sizing in kWp, panel count and inverter configuration, derived from the measured load curve rather than a rule of thumb
• Estimated annual production in kWh, using yield by zone rather than a single national factor
• CAPEX in Chilean pesos, all-in: engineering, equipment, mounting, construction and SEC filing
• The regulatory route: Net Billing self-consumption under 300 kW, or PMGD above it, with the filings each one requires
• Tax treatment of the investment: for companies under the Pro Pyme regime (Article 14 D No. 3 of the Income Tax Law), instant depreciation, to be confirmed with your accountant
• Scope and cadence of operation and maintenance, including Performance Ratio reporting

The equipment we specify and the warranty attached to it are published in Spanish on the SEC-certified Tier 1 panels and inverters page and on the warranty terms: 3 years on the installation, plus the panel and inverter warranties. If you are still choosing a supplier, the comparison between SolarPro and Copec Flux sets out how the two offers differ.

Which regulatory route are you asking about?

Tell us in your message, because it changes the whole proposal. Under Net Billing — Law 20,571 as amended by Law 21,118 — you self-consume and credit surpluses against your own bills, with a cap of 300 kW per connection point, a TE4 declaration to the SEC and the SEC connection filing with the distribution utility. Above that threshold the route is a PMGD under Article 149 of the General Electricity Services Law and Supreme Decree 88 of 2019: up to 9 MW injected into the distribution network, with a feeder capacity study, coordination with the Coordinador Electrico Nacional and a choice between spot price and the stabilised price set every six months by the CNE.

The distinction is simple in practice: Net Billing reduces a cost, a PMGD produces a revenue. Both are documented at length in Spanish on the industrial EPC and PMGD page and on the PMGD distributed generation project page.

If the site has no grid at all — a remote mining camp, an exploration front, an irrigation pump — the question becomes on-grid versus off-grid instead, covered in our guide to on-grid and off-grid systems in Chile. Two further pieces worth reading before you commit are the guides to monocrystalline versus polycrystalline panels and to solar panel maintenance in practice, which is what determines whether the yield in the proposal survives year five.
