Solar energy is the one of the most succeeded efficient renewable energy sources harnessed by people in current times. The energy potential of solar energy is great. The type of solar energy capture system to be installed depends on the consumer's requirements. A typical installation involves the panels, which are a set of several individual silicon-based photo voltaic cells and their support structures, along with an inverter, electrical conduit piping and AC/DC disconnect switches.
These systems can be costly but are a more cost-effective alternative to electrical circuits.It is better to opt for a higher Watt power module as they have higher Watt power capacity, hence cheaper per Wp as compared to modules with lower Watt power capacity. The efficiency of solar panels is also better for modules of higher Watt power owing to the quality of photo voltaic cells used, hence making its output exceed the rate of input.
Before jumping on to the solar panel bandwagon, here are five questions to keep in mind -
Is your house solar conducive?
This is the first thing one needs to know before installing Solar Panels. In fact, most people make the mistake of installing panels without analyzing the parameters and the requirements. This defeats the purpose of installation as without proper adherence to the required parameters one cannot utilize the efficiency of the solar panels. Shading, roof direction and roof structure must be taken into consideration with the optimal condition being -- shade-less, north facing roof with an inclination of 10? to 30? to help rain water clear away the debris.
What is rate of consumption at your home?
As Solar Panels allow you to pick your choice of outlets, you can customize them per needs, selecting either one set of appliances or the entire house. It is essential to monitor your electricity consumption and set the solar harnessing plan accordingly. An average solar cell provides approximately 0.5 volts and an entire solar panel is made up of anywhere between 36 and 72 solar cells. This can help you estimate how many panels would meet your total electricity consumption per day/month/year.
What type of Solar Panel are you opting for?
Solar Panels are largely categorized into two types- mono crystalline and poly crystalline Solar Panels. The former has a blackish tinge to it, while the poly crystalline has an overall bluish hue, with the shades of blue differing from cell to cell. It is a common misconception that mono crystalline solar panels are more efficient than poly crystalline ones. Instead, every Solar Panel must be examined carefully, to measure its efficiency.
What are the warranties available?
The Solar Panel, under ordinary circumstances, can last for upto 25 years. As long as you purchase the solarset up from a reputed supplier, you will be guaranteed long lasting performance without glitches. Always opt for a solar setup that is secured under a warranty period and remember to ask for the certificate to ensure remaining insured if malfunctioning happens.
How much would the Solar installation cost?
The cost of a Solar Panel purchase and installation may vary between Rs 40,000 and Rs 6 lakh. Solar power reduces the dependence on electricity from the power grid and, hence, saves money in the long run despite the initial investment in installation. Yet, the price can be considered too steep and deter people from the larger benefits. Set aside a budget and look for solutions within that range to narrow down your search.
Eventually, inspecting the panels regularly is recommended to prevent a small issue mushrooming into an expensive problem in the future. With correct implementation, along with timely maintenance, solar panels can assist consumers in curbing extra expenditure and increase savings
