Things To Know Before You Switch To Solar Energy

What will be investment to install solar system in the house?

The cost of installing solar power system will be a bit high. However, you should keep in mind that this investment will soon be offset by the power saving that you will make in the long run. On an average a 2KW solar electric system will cost around $20,000. This includes the cost of various components such as solar panels, panel mounts, and inverter and of course, the installation charges.

You are also entitled to get tax break for installing solar panel in the house. Moreover if your house is also connected to utility grid besides being powered by sun’s energy, then you can get another benefit out of it. If your panels are producing more power than is required by the house, you can send the surfeit amount to the utility grid. For supplying power to the grid, you would receive credits through net metering.

Will a solar power system help you to cut down your utility bills?

A study conducted by an organization infer that in the biggest cities of if the US, where customer invested in a 5 kW solar PV system, a saving between $ 44 and $ 187 per month were made during the first year of owning the system. This is quite amazing.

However it is wise to remember that with regards to saving lot depends on factor such as on how much electricity you use and how efficient the appliances are that you operate. In summers you can expect your solar power system to produce more power which will offset the production levels in winter. However an efficient system can reduce your home’s energy bill by over two-thirds.

 What’s the difference between solar photo voltaic system and solar hot water systems?

Both of these capture the sun's heat and light to serve their purposes. The solar photo voltaic systems use photo voltaic panels to produce electricity. On the other hand the solar hot water or thermal systems capture sunlight to heat water. This water can both be used for domestic use, to heat pools or to heat the house through radiant heating.

Are solar powered radiant heating systems efficient?

Yes, absolutely. The solar energy is used to heat water. The water is transferred to narrow tubes that are embedded under the floor. The heat from the tubes rises up to make the rooms warm. Radiant floor systems are typically 40% more efficient than their forced air counterpart and can be zoned to match thermal comfort to each room.

How much maintenance does solar energy panel require?


The solar photo voltaic cells need minimum maintenance. They are placed upon the roof or on the ground where they have good exposure to the sun. The do not need frequent washing or dusting. But if you live in a dusty area, you can wipe them from time to time. If you find snow or dry leaves cluttering the panels, remove them. Your panels should be positioned so that there are no trees or other kinds of shades obstructing the sunlight from reaching it.

Similarly, the solar hot water collection arrays don’t need much maintenance either. You can clean the tubes occasionally with window-wash brush and biodegradable soap.

Will I need a building permit to install a solar energy system in my home?

Yes. You’ll need to obtain building permits to install a solar photo voltaic or solar hot water system. There are specific codes for building, electrical, and plumbing to install a solar power system. However installing solar power system does not need radical techniques. Most jurisdictions have building codes that are compatible with solar energy technology. Your installer will quote a price that will include everything from the cost of getting the permit to installation price.

How long will it take to install a solar power system in my home?

The professional would come to your house and survey it to find the optimal spot for laying the panels. They will configure a design and custom order for your solar energy system. All this will take a few weeks’ time. Installation will take few days’ time or less than that.

What is a net meter?

This is a very good mechanism. Some homes are powered by the solar power system as well as are tied with utility grid. In case the solar power system is producing more power than required by the house, then the surfeit power can be sent to the utility grid. In that case if the house has a net meter then it will show how much power the consumer used and how much has been given off to the grid. When the meter spins forward it means you are drawing from the grid. In case power is being given off to the grid, it will spin backward. On average, only 20-40% of a solar energy system’s output ever goes into the grid. Exported solar electricity serves nearby customers’ loads. If you supply power to the grid you would get credit from the utility company.

Net meters look very much like other outdoor meters. The only difference is that they spin both forward and backward.

Do I need battery backup for my solar panels?

It is not very essential. A solar power system with battery backup will add 25 % to your investment cost. A battery backup is required in case the system is nottied to power grid. If your locality does not have problems of long utility outage you don’t need a battery backup. Battery-tied systems are not necessarily more efficient.

How much space do I need for a solar photo voltaic system?

On average a 1000 watt system may need 100 – 200 square feet of area. This would also vary slightly with type of module that you purchase.

Is the house fit for installing solar power system?

Here are a few things that you should check to know it-
• Does the house have a good southern exposure?
• Is the exposure free of all clutters and trees that can guard sunlight from reaching the panels or drop debris upon them?
• The pitch of the roof is important. Most roofs, from flat to 60-degrees can accommodate photo voltaic panels.
