Solar For Schools & Collages
Price On RequestPower Source: Solar
Schools and colleges in India are ideally suited for rooftop solar power plants. Typically, they have large roof area; a large proportion of their electrical load is during the daytime; and they have very little air conditioning load. Grid-tied solar system could be the best option for schools and collages as the excess power generated during the holidays can be monetised to offset other costs. Benefits
Energy security Rooftop solar plants can deliver power during load-shedding, ensuring that critical loads are always running. Grid-tied solar plant configurations cannot deliver power during load-shedding.Cost-effective Roof top solar power is much cheaper than the diesel power and grid. Additionally, your energy cost is now fixed for the next 25 years, unlike diesel and grid power which keeps increasing. Net metering can ensure that excess solar generation (such as during holidays, when loads are low), can be monetised.ReliableA solar power plant has no moving parts, ensuring reliable power over 25 yearsMinimal maintenance A solar plant requires very little maintenance from the energy consumer Flexible configurations Solar panels can be installed on different kinds of roofs, including covered parking areas, as long as the structure can bear the weight of the panels. They are also highly scalable, with rooftop plants ranging in capacity from less than 1 kW to more than 1 MW
Limitations
Required rooftop space The capacity of the solar plant that can be installed in an office building may be constrained by lack of sufficient shadow-free rooftop space. Typically you will need about 100 SF of shade-free roof area for 1 kW of solar panels. Insufficient roof area will mean that the capacity of the solar plant on your roof may be sufficient to meet only part of your electrical load. Additionally, in multi-tenant office buildings right to use the available space may be a constraint. Inconsistent power Solar power is dependent on the sun shining, and output varies depending on meteorological conditions e.g., passing clouds can temporarily reduce the solar plant s output. Therefore solar power for critical loads should be used in conjunction with another source of power such as battery backup.Only daylight power Solar power is only available when the sun shines. Therefore night time applications will require other sources of power, or power from batteries charged through solar.Heavy loads Air conditioning is usually the heaviest load, accounting for more than half the energy consumed. Small Banks with few air conditioners require installation of large solar plant. By keeping these air conditioners on the grid power while offsetting its consumption through net metering reduces initial investment. Elevators may not run on solar and will require grid or DG as another power source.
