How solar works

Solar power systems01–03

Grid-tied rooftop solar panels on a tile roofGRID-TIED

On-Grid Solar Power Systems

Your panels power your home during the day and work together with the utility grid. The most affordable way to cut your electricity bill.

Best for
Homes and businesses with high daytime use
Brownouts
Shuts off for safety; no backup
LiFePO4 solar battery bankBATTERY ONLY

Off-Grid Solar Power Systems

A self-sufficient system with batteries and no utility connection. Ideal where the grid is unavailable, unreliable or too costly to bring in.

Best for
Farms, resorts, remote sites, rest houses
Brownouts
Not affected; runs on your own power
Deye 12kW hybrid inverterGRID + BATTERY

Hybrid Solar Power Systems

The best of both: solar savings with the grid, plus battery storage that powers your home at night and keeps the lights on during brownouts.

Best for
Homes that want savings and backup power

Ask our engineers
How much does solar installation cost?

It depends on the system size (kWp), the type of system (on-grid, off-grid or hybrid), battery capacity, roof type and site conditions. A hybrid system with batteries costs more than an on-grid system of the same size.

The best way to get an accurate price is a free consultation. Share your monthly bill and we will prepare a quotation for your home or business.

How many solar panels do I need?

We look at your monthly consumption in kWh (found on your electricity bill), when you use the most power, and your available roof area. From there we calculate the system size and the number of panels. Higher-wattage panels mean fewer panels for the same capacity.

Can solar panels work during brownouts?

It depends on the system. A pure on-grid system automatically shuts off during a brownout. This is a safety requirement so no power flows back to linemen working on the grid.

Hybrid and off-grid systems have batteries, so your backed-up loads keep running during a brownout.

What is the difference between On-Grid and Hybrid?

An on-grid system has no battery. It reduces your bill during the day but gives no backup power. A hybrid system adds a battery, so solar energy you don't use during the day can power your home at night and during brownouts. Hybrid costs more upfront but gives you more independence.

Can I still receive an electricity bill with solar?

Yes, if you stay connected to the grid. You will still use some grid power, usually at night or on cloudy days, and your utility may charge fixed fees. The difference is that the bill becomes much smaller. Only a fully off-grid system has no electricity bill.

What is Net Metering?

Net metering is a program under the Renewable Energy Act that lets you export unused solar energy to the grid. Your distribution utility installs a bidirectional meter and credits the exported energy against your bill. iSOLAR can help you prepare the application requirements.

How long does solar installation take?

Most residential installations take 2 to 3 days on site once materials are ready. The full timeline, including site survey, design, equipment delivery and (if applicable) net metering approval, is longer. We give you a schedule with your quotation.

Does solar require maintenance?

Very little. Panels should be cleaned periodically, since dust and bird droppings reduce output. We also recommend a regular check of connections, the inverter and batteries. iSOLAR offers inspection and maintenance services for this.
