Solar Design Chile

Energy Usage

Your daily energy consumption determines the optimal solar system size for your home in Chile. Most households in Chile use around 15 kWh per day, whilst energy efficient homes can reduce this to roughly half.

Lowering energy usage before solar installation—via improved insulation and efficient appliances—often reduces required system size and enhances financial returns.

Typical energy usage per person per day in Chile:

Low (Efficient)
~3 kWh
Medium (average)
~4 kWh
High (intensive)
~6+ kWh

Note: Actual usage varies depending on property size, building efficiency, climate, and appliances.

Solar System Sizing

To offset your average consumption, you'd need roughly 3.9kW of solar capacity. Sizing your system between 5.9kW and 7.9kW accounts for daily and seasonal variations in solar generation.

In Chile, a 6.6 kW installation produces around 28.4 kWh per day on average, though output ranges from 3.46 kWh/kW/day during June to 4.83 kWh/kW/day in October.

A 6.6 kW system in Chile can generate approximately 0 kWh annually based on local sun conditions.

Solar & Energy Savings

Calculate Heat Pump & EV Savings

Electrify your home by replacing gas heating, petrol vehicles, and other fossil fuel appliances with electric alternatives powered by clean solar energy. This delivers significant additional financial savings and substantial carbon emission reductions. Our calculator helps you compare costs and model the financial impact of switching to electric appliances and vehicles.

Calculate Electrification Savings

How Solar Reduces Your Electricity Bills

The calculations below show how your electricity bills change with solar. Your Old Bill of - per month (- annually) is calculated from your total energy consumption multiplied by the grid electricity rate. Your New Bill of - per month (- annually) accounts for solar generation, the percentage you use directly (self-consumption), remaining grid consumption, and feed-in credits for excess energy exported to the grid. This results in monthly savings of - (- annually).

Battery Storage Chile

Solar Battery Sizing

A 6.6 kW solar-only setup in Chile delivers around 50% self-sufficiency, leaving 50% dependent on grid electricity. Adding a 10 kWh battery increases energy independence to approximately 99% annually, reducing grid reliance to 1%.

Solar & Battery System Cost Chile

Understanding Solar & Battery System Costs

Solar systems in Chile are priced around $5,722,788 for a 6.6 kW installation, rising to approximately $10,196,755 when including a 10 kWh battery. Solar installations typically pay for themselves within around 7.2 years, whilst batteries extend payback but deliver significantly higher energy independence.

Cost estimates cover equipment, installation labour, and applicable taxes. Modify the system size and battery storage sliders to explore different investment levels and payback periods.
