Frequently Asked Questions: Roof TOP SOLAR
The Solar plant will generate electricity only during the Sunny hours, typically between 6 A.M. to 6 P.M and will not generate any electricity during the night.
Will I face problems of Voltage fluctuations and tripping if heavy loads like AC are switched on ?
Amplus offers a Grid Interactive Rooftop Solar plant which matches the frequency and voltage of your Grid and Diesel Generator and runs in sync with them. The electricity created by the solar plant is exactly like the one you are sourcing from Grid/DG and it will be fed in simultaneously with them. Thus, there will be no voltage fluctuations and you can use/connect any number of heavy loads equipment.
Since Solar PV works based on the amount of sunlight it receives, it starts generating the output at around 6 am in the morning and stops at about 7 pm in the evening depending on the plant location. The generation increases gradually and peaks at noon and then gradually decreases as the Sun goes down. Since its a grid interactive plant the functioning of your electrical equipment is not affected.
Technically yes, a solar plant can meet your entire power requirement if it is backed by battery energy storage system (BESS). But practically, for commercial and industrial users where the power requirement is higher, it would be recommended to use solar in sync with the grid. When in sync, priority is automatically given to the solar power to be consumed first.
Solar Power is an intermittent source of energy depending on irradiation, the temperature of the region and a lot of other environmental factors. Hence, a 100 kW plant wont produce 100 kW power.
The annual maintenance cost is not very significant as the system only requires cleaning of modules (every 2-3 weeks) and basic preventive and corrective electrical maintenance (every 3 months) Water is generally used to clean the panels Typically 5 litres of water is required for a KWh. Amplus will take care of the operation and maintenance of the plant at its own cost for the tenure of PPA tenure.
Following factors should be kept in mind:-
Location and layout of the solar plant.
Roof Orientation and shade-free area.
Quality of equipment
Design of the solar plant.
Maintenance of the plant.
A proper evaluation will be done by Amplus to see if the solar plant can be put up on your premises.
If your roof is not having any shade from adjacent buildings, trees etc and its structure is not delicate then your roof is suitable for installation of solar plant. Solar plant can also be installed on car parks, open shade ground within your premises by erecting special mounting structures.
It can range between 2-10 weeks depending on the complexity of the project
On an average, every 1 KW setup produces 1300 to 1500 units in a year. This may, however, vary based upon the location of the plant, seasonal factors, surroundings and shadow-free area available. You can consider 1400 units for sake of calculations.
This would depend on various factors such as the shadow-free area available, the orientation of the roof etc, however, as a thumb rule, we can assume 1KW plant requires 12 sq meters of shade-free area.
Amplus uses non-penetrating structures which are mounted without any puncturing. Thus, the integrity of the roof is maintained. The load of the entire solar plant is about 10-15 kg/square meter and can easily be taken by any roof
It is advisable to install an energy monitoring system along with your solar plant that will allow you to compare the actual with the estimated performance on daily, monthly and annual basis.
he electricity generation of the plant suffers during rainy and cloudy days especially during the monsoon season, but the generation never drops to zero. The loss of generation during monsoon and other rains is already adjusted in the 1.3 to 1.5 Lakhs unit/100kWp/annum generation number.
No, Solar energy is integrated into the LT panel of consumer premises, wherein DG, Grid or other generator sources would be feeding power as of now. When solar energy is injected, the equipment is unaware of the source from which power is feeding in. Hence it is not possible to segregate the loads on basis of the power source.
No permissions are required if you are installing an off-grid solar PV system. But in case you wish to integrate your solar system with the grid to avail net metering option, certain permissions are required to be taken from the respective DISCOM and the state government.
