Chile

How the Chilean market works

Households buy electricity from a distribution company under regulated tariffs. The CNE (National Energy Commission) sets the technical and pricing rules and the SEC supervises installations. The net billing scheme has grown quickly: 466.7 MW and 39,636 installations in April 2026 according to SEC data (Reporte Minero), and 502.9 MW by 31 May 2026 according to the solar association Acesol (pv magazine).

Solar in Chile is strongest in the north and centre, where sunshine is plentiful. Rising electricity bills and falling equipment costs are the usual reasons households install solar.

Net billing: how exports are valued

A CNE presentation describes the scheme: injections are valued at the same price distribution companies pass to their regulated customers for generation, adjusted for the lower losses that injections cause. The credit appears as a discount on the bill, and a remaining balance that cannot be offset can in some cases be paid in cash, though the scheme limits cash payments to favour self-consumption (CNE presentation).

A policy database describes the eligible size as up to 300 kW, and explains that, unlike net metering, net billing separates consumption and injection, so you pay the full retail price for what you import even if you inject the same energy later (Energy Solutions policy database).

That is the economic case for storage: every kWh you use yourself avoids the retail price, while every kWh you export earns a lower credit.

Storage and the law

Law 21.505 (2022) added storage systems to the general electricity law to encourage their use, according to a University of Chile thesis that analyses the economics of residential batteries (University of Chile).

For installations, the SEC approved RGR Technical Instruction No. 06/2021 (SEC Resolution 8,454 of 2021), which sets out the design and execution of battery energy storage systems in electrical installations (vLex). Ask your installer to confirm that the installation follows it, and whether the SEC declaration for your net billing system must be updated when you add a battery. We could not confirm the current forms.

Does a battery pay?

A solar installer quoted by El Desconcierto says that under net billing a battery lets you avoid selling energy at the lower price and use it at home, and estimates savings of up to CLP 60,000 on a family's bill (El Desconcierto). That is an installer's estimate, not an independent one.

We do not state a payback. It depends on your tariff, how much of your use is in the evening, the quote and how much solar you already have. Use the calculator below with your own bill.

Blackouts and backup

During the latest widespread blackout, users with net billing and storage were able to keep supply for longer, according to Reporte Minero (Reporte Minero). Backup only works if the inverter can run on its own: a grid-tied inverter normally shuts down when the grid fails, so ask for a hybrid or backup-capable inverter with a backup circuit.

Size the backup circuits for the loads you need: lighting, fridge, router, pump and heating controls. A battery cannot run an electric heater or a large oven for long.

Tax, duty and incentives

We could not confirm VAT treatment, import duty or any grant for household batteries in Chile, and the tax and customs authorities' pages were not among the sources we could read. Ask the seller to show VAT on the invoice and whether the goods were imported with duty, and ask a local accountant before you rely on any relief.

Portable power stations versus a home battery

Search interest in Chile is strongest for portable power stations (in Spanish, often 'estación de energía portátil' or 'batería portátil'), which are used for camping, remote work and outage backup. A power station is a battery with sockets that you can use immediately. It is not wired into the house and does not earn export credits.

A home battery is installed by a qualified installer, can run whole circuits and works with net billing. Choose a power station for portable backup of a few devices and a home battery to shift solar into the evening and back up the house.

Outside Chile

Rules, tariffs and incentives for home batteries differ from country to country, so do not apply the figures on this page to a home elsewhere. We are adding guides for other countries to this section.
