When we hear or discuss solar power systems, there are always a few questions which pop-up in your mind.
Let’s discuss a few common questions encountered while buying a solar power system for your residential purpose:
1. What Size of Solar Power System Do I Need?
The requirement of the solar power system depends upon the utilization of electricity at home. It is also related to your connection load provided by the regional discom. The size of the system is based on below aspects:
- Household electricity needs
- Area of roof
- Location
- Angle of roof and load connection
2. How much Money will I Save by using Solar Power System?
Solar power system will help to save money on electricity costs as long as you live in the same house for such a long time to recover the installation costs through savings on your power bill The cost of electricity is rising, so the more you can generate your power, the more you’ll be saving
The best part is, most of the panels last for 25-30 years; hence you can earn handsome returns for 18-20 years.
Your rate of return will be dependent on financial and environmental variables. Some of these variables include:
- How much you currently pay your utility for electricity
- The cost of the solar energy system
- How much energy your solar power system will generate every year
- The solar energy rebates and incentives you receive
3. Do I Need a Solar Storage Battery?
There are different types of solar power systems, and grid-tie or On-grid solar power systems are the most common and vastly used by homes. These systems don’t need batteries and use standard solar inverters and connected to the public electricity grid.
An off-grid solar power system is not connected to the electricity grid and hence requires battery storage and designed so that it will generate enough power throughout the year and have enough battery capacity to meet the home’s requirement.
The high cost of inverters and batteries mean off-grid systems are much expensive compared to on-grid systems and hence are usually only needed in more remote areas that are far from the electricity grid.
4. Installations and Warranties
The solar power system consists of solar power panels, a mounting structure, and a solar inverter with a computerized controller. A solar panel produces DC electricity from sunlight. Then the inverter converts the generated power into AC so that it can be used in a household.
Usually, a solar power system warranty is offered for the panel, inverter, support equipment and others. Solar panels come with a warranty of 20-25 years. Its breakdown is as follows:
Ten years on the product
- 15 years for providing 90% of its peak energy output
- 25 years for delivering 80% of its peak energy output
