Harnessing solar power to fulfill domestic requirements is a noble idea, albeit an expensive one, as it is beneficial to the surroundings. However, in order to switch over from normal electricity to solar power, some preparations within the house would be necessary and this basic setting up is explained as follows:
• The first step entails estimating as accurately as possible the power consumption of the household for daily, monthly and yearly durations. This could be done by either maintaining a record of electric bills over a period of time or following the relevant methodology and formulae and calculate the amount.
• Next, it is time to decide on the power supply system which would not only cater to all the domestic needs but would also exceed the total requirement by a wide margin of 30%. In such a situation, a combination of solar power and grid power is recommended.
• A house which has to derive its electricity from solar power would need to be installed with solar power panels on its roof and these should be purchased after ascertaining certain facts like every single panel should be capable of producing 250 Watts of direct current at its peak, is subject to 0.5% depreciation with each passing year and can last up to 30 years at a stretch.
• For the solar power panel to act as a strong back-up supply there should be at least 20 panels with each producing 250 Watts of current so that the daily minimum of 5000 Watts of power is harnessed every day.
• Nowadays, solar power panels come in DIY kits so installation is nothing more than simply following instructions which come with the package. It is the direction of the panel which matters and the onus is on the user to ensure that his roof is not shaded and that the panels get optimum exposure to the sun.
• While a combination system ensures grid power at night, in case of only solar energy it would be advisable to invest in a battery bank system which would look after the electricity needs during the night.
• Before embarking on usage of solar power it is imperative for every user to be aware that the electricity generated through solar panels is in form of direct current while that which is used in households is alternating current. Thus from the panels it is imperative for the electricity to pass through the power inverter before it is ready to be used.
• From the inverter the power goes to the electric service panel of the home from where it is distributed to all the points within the house. There should also be a provision of a switch so that the supply can be shut off when not required.
