Frequently Asked Questions
FAQ1.Which roof types are appropriate for rooftop solar systems?
Any type of roof with appropriate load bearing capability, such as RCC, tin shade, etc., is suitable for the installation of rooftop solar PV systems.
2.Why do the solar panels need a shadow-free area?
For solar panels (and the cells inside) to generate the most electrical energy, sunlight must be received continuously. Even a little amount of shadowing causes a significant reduction in generation, squandering installed system capacity. Additionally, a prolonged (regular, albeit intermittent) shadow on some cells or modules significantly shortens their lifespan, causing black patches and rendering them worthless far earlier than their typical lifespan of over 25 years.
3.How much energy is produced per day by a 1 kWp solar power plant?
A 1 kWp solar power plant may produce 4 to 5.5 units per day on a clear, bright day.
4.Will my solar rooftop system supply me with constant energy generation throughout the year?
No, the solar rooftop system's daily energy production will rely on factors like temperature and sun irradiation, among others, and they may not be constant from day to day.
5.Will my solar rooftop system provide the same amount of electricity each year for the next 25 years?
No. Degradation is the loss of a solar module's generating capability due to exposure to sunshine and the outside environment. Solar panels typically deteriorate by 1% year.
6.What elements have an impact on generation?
- Plant geography
- equipment quality
- sunlight hours
- workmanship
- PV module tilt angle and orientation
- module cleaning;
- operations and maintenance activities, etc.
7.What benefits do Grid-Connected Rooftop Solar Systems offer?
- The consumer saves money on their power bill
- There are safeguards against increased electricity usage
- Vacant roof space is used, so no more land is needed
- There is a short gestation period
- There are three times as many returns as fixed deposits.
- Transmission and distribution (T&D) lines are not needed in greater quantities.
- An increase in system efficiency and a decrease in system congestion.
- 25+ years of useful life
- environmental security due to a decrease in carbon emissions.
- Improved DISCOM/utility management of daytime peak loads.
- Fulfillment of obligated organisations' Renewable Purchase Obligations (RPOs).
8.What components of an on-grid rooftop solar PV system need operation and maintenance?
Solar PV systems require extremely little upkeep compared to the majority of other power generation methods. A PV plant must, however, be properly maintained in order to maximise its lifespan and energy output. Typical maintenance tasks could include, but are not limited to, the following:
Periodic module cleaning is necessary (dust, bird dropping and other debris can cause decrease in power generation). Periodicity is influenced by local factors such as dust, wildlife, air pollution, etc.
- Other items should be checked periodically as stated below:
- Checking module connection integrity
- Checking junction boxes / string combiner boxes
- Inspecting mechanical integrity of mounting structures
- Tightening cable connections that have loosened
- Replacing blown fuses
- Repairing lightning damage
- Other items should be checked periodically as stated below:
9.Monkeys can be seen in our neighbourhood. Would they endanger the rooftop solar system?
The hardened or tempered glass top of the solar modules makes them resistant to breakage by falling items or monkeys. If someone purposely throws stones at them, they can be broken. One way to prevent the monkey threat is to cover the surface of the modules with wire mesh, although this is not advised because it frequently creates shadows on the modules.
10.What will happen to RTS if I move my house or workplace where it is installed?
It is simple to disassemble the system and rebuild it elsewhere. Therefore, it may be moved to your new home.
