On -Grid Solar Systems are essentially installed in Residential, Commercial and Industrial buildings where regular power supply from State providers is available. This system can be upgraded to a hybrid system with battery backup.
Lower equipment costs as compared to Off-Grid Solar.
Reduce the burden of high tariff electricity bills, year on year tariff increase (avg. 5%).
Off-Grid Solar Systems with battery backup are essentially installed in locations where there is no state Net-Metering Policy or the Grid is not reliable with frequent power cuts.
Most suitable for remote installations where power is not available or unreliable with frequent power cuts.
Customers can size the battery bank as per needs.
Consistent supply of electricity is a basic requirement whether it is for hindrance-free education, seamless business operations or reducing maintenance overheads. Soaring electricity bills, increasing power outages and deteriorating environmental conditions, make solar energy the most viable and long-term solution. We at Eirsun, constantly strive to provide our customers with a customized solution that helps them seamlessly migrate to Solar Power.






As a simple rule of thumb, 100 sq ft. of shadow-free roof can accommodate 1kW of solar panels.
Solar panels are compatible with most types of roofs. The best type of roof for solar panels is a south facing roof devoid of shadow-casting obstructions. Solar panels tend to generate more electricity when they face the sun when it is at its most intense for the longest period. If you have a shadow-free area available on your roof you can schedule a site survey and let our experts assess your roof’s solar potential. During a site survey, our solar experts assess unused rooftop area for incidence of shadows through the year. They can advise you on the best way to maximise electricity generation and can also recommend suitable technologies to boost your supply. Whether your roof is concrete, metallic or non-metallic, our experts can advise you on the best way to mount the solar panels on the roof.
Whether you are a homeowner, a business owner or an SME (Small & Medium Enterprise), going solar can eliminate your electricity bill or reduce it significantly so that electricity costs are no longer a major factor in your monthly expense.
Your savings from solar depend on factors such as:
Since the savings you realize are the electricity costs that you avoid by going solar, you will save even more if the electricity tariffs are high in your region and when they continue to rise year-on-year.
Going solar will protect you from the rising electricity costs and will grow your savings over 25+ life of your solar panel system.
