In today’s world, we all are affected by rising fuel prices. This definitely calls for urgency to search for an alternative electrical power source for residential properties which will help in saving a lot of energy cost. While contemplating to make the best choice- two of the most obvious options that strike are either considering a wind power system or the solar power system.
Opting for any of the above-mentioned alternatives are going to stretch your finances. However, you should know that tax and subsidies are available on both of these options. A lot of people prefer residential solar power systems due to various reasons.
The foremost reason being, that solar is available in abundance and everywhere. Solar energy is available in adequate intensity in most places where even electricity does not exist. The best part is that you do not have to deal with any hassles such as authority clearances, dealing with any legal formalities, complains from neighbors and a lot of other things.
How do solar power systems work?
Basically, solar power systems allow you to plan for a basic installation. As and when you gain more experience you can continue to add on which is how you can have less economic constraints. Solar power systems also look aesthetically more appealing.
Let us have a look at the three configurations of residential solar power systems that you could consider.
1. Stand-alone system: If you live in a residential area which is not served by any utility grid, a stand-alone system is the only choice that you have. Keep in mind that your solar power system will be the only source of electric power for your house. A stand-alone system will be less costly and very simple to manage.
Some people go for a stand-alone system even when they have a utility supply available. When this is done, it might happen that the residential solar power supplies power only to some of the household appliances and the rest of them remain connected to the utility supply.
2. Grid-connected solar supply: Grid-connected solar supply system comes with a battery backup. If your house is already served by utility supply then it is best to install grid-connected solar supply. The solar supply of your house will solely depend on the extent of solar supply available. In case you require more power, then these needs will be met by your solar system which will draw power from the utility.
With its battery backup, you are free from utility supply outages. However, when utility supply outage occurs the stored electricity can be at your rescue by providing electricity to your essential appliances at least. In case your solar power system generated excess power you can supply the excess power to the utility grade and you will get paid for it.
3. Battery-less grid connection: When you choose to install a battery-less grid system, this system can prove to be much cheaper. This is because you don’t have to pay any extra cost for the battery, battery charger etc. However, this system will not allow you to be free of utility outrages but you will still be able to supply the excess generated power back to the utility and gain credits.
Out of all the three alternatives mentioned above- stand-alone residential solar power system is the cheapest. The grid-connected solar power system with battery backup is the costliest- but obviously, it has its own perks.
Wrapping it up
With the fast dwindling fossil fuel resources and rapidly increasing need to cut down on carbon emissions for a better lifestyle- it will be prudent to have a long term view and adjust accordingly so that the dependence on power supplies from utility companies is reduced.
