How To Get The Most Out of Your Residential Solar Power System
Tips to use solar PV system in an efficient way at home so that you can get the most out of your solar investment.
Installing a solar PV system for your home is a great way to reduce your electricity bills. However, there are ways you can get the most out of your system, maximise your savings while doing your bit to help save the environment!
Every solar energy system is designed to give best results keeping in mind specific power requirement and purpose. Once installed, it’s not just the PV system design but also the power usage behaviour that directly impacts the monthly power bill.
You can make the most of your solar investment if you:
- Consume as much of the generated solar energy as possible, and
- Purchase minimum electricity form the main grid as possible, as you’ll have to pay standard rates which is much higher than per unit cost of solar electricity.
At Insolergy, after every residential solar energy system installation, we share the following tips to help homeowners maximize the solar system output.
Tips for efficient use of residential solar power system
Be a smart power consumer by adopting power saving behaviors
In order to avoid wasting electricity:
- Use LED lights. They might cost more than the conventional CFL lamps, but they save electricity in long term, and typical cost recovery is within 1 year. Additionally, many good brands offer product warranty of as much as 5 years.
- Use energy efficient appliances, with higher BEE (Bureau of Energy Efficiency, GoI) Star Rating, viz. Refrigerator, Air Conditioners, Electric Geysers, etc.
- Do not open refrigerator frequently or for longer periods. Same rule applies for Air Conditioner as well – ensure keeping the windows and doors shut when AC is running. Almost all ACs now come with timer functionality and Economic mode – allowing better control on cooling and power consumption.
- Stop leaving electronic items on/plugged in overnight when they are not in use
- Avoid leaving the lights and fans on in an empty room
- Don’t fall asleep with your television on.
The next time you buy an appliance for your home, here are a few things you can keep in mind:
The Bureau of Energy Efficiency rates appliances for their energy efficiency and this rating is known as the BEE star Rating. Check this rating on the appliances you plan to purchase as higher the number of stars given, higher its energy efficiency.
Opt for newer models as they tend to be much more energy-efficient than older editions of the same appliance. For e.g. if you need a new refrigerator, take the opportunity to upgrade to a more efficient model
Maintenance and Monitoring
Solar panels use sun light to generate power. The lesser your panels’ exposure to sunlight, the lesser power your solar PV system will generate. This is why cleaning your solar panels regularly is crucial to maintaining system efficiency.
There is very little involved in this process as panels are low maintenance after being installed. If your system is of or below 5 kWp (approx. 350 sq. ft. of net panel area), then you can very well maintain and clean the panels yourself. Bird droppings and dust are usually the only things that come in the way of your system operating at full efficiency. Here’s how you can clean solar panels without professional help.
For larger installations, like solar for housing societies, solar companies like Insolergy provides AMC that includes periodic PV system inspection, energy production reports as well as troubleshooting services. For instance, Insolergy recently installed a 30.40 kWp solar power plant for a housing society in Pune. To ensure effective operations of the system, we installed real-time online monitoring system to monitor the system performance. It was integrated with a weather monitoring tool to identify the cause of loss of solar power production.
