|Home Solar System|
As solar technology improves, average homes can generate electricity by themselves. Nowadays many residents across the world turn to residential solar power, while others seem to have no any intention of joining the fashion show. Why? The following are seven elements that can probably answer this question. Let’s take a look at them.
1. How much does it cost?
On average conditions, if a home is intended to go solar, it needs a system called solar PV system to do the job. This system consists of solar panels, PV inverters, a two-way power meter, batteries (optional), Wi-Fi kits (optional) and so on. Besides, you also need to employ laborers to install it for your home. Therefore, the total cost cannot be too cheap. Generally speaking, if you want to build a system that is capable of generating 6,000 kWh of electricity or so, you probably need to build a 5 kW system. This may cost about 50,000 - 60,000 dollars in the US and about the same number of Chinese yuan in China.
2. Someone says this is an investment, is this true or just a rumor?
To be frank, it is an investment which lasts for about 5 to 6 years or so. How can it become an investment? Thus, you need to learn what net metering is. It is a policy which allows your home system to connect to the local utility grid under the rules and laws of the local government, which pays you back after you have fed back your unused solar electricity to the grid and asks you to pay when you system cannot generate enough electricity and needs electricity from the grid. Global residents usually install the grid-tie system which is in accordance with the policy. But if you install an off-grid solar power system that needs batteries, you don’t need to care about this policy at all. You are completely independent of power consumption.
3. Will the future of distributed solar power generation become pale or more prosperous?
Indeed this is a very difficult question to answer, but we can analyze it. Distributed solar power generation includes residential solar and is a way of generating power by installing solar panels on the rooftops of all kinds of buildings or on other object which are suitable for this installation. Today, the UK, the US, Japan, Australia and Canada are famous for this way of power generation. Countries like China and India are encouraging their residents and factory owners to install it. Now the European market is falling, while the East Asian market is rising fast. The future for it is bright. Home solar will become cheaper as mass production of residential solar products continues.
4. Have you seen solar PV firms around your community or living place?
In common conditions installing this system needs professionals. If they are around you or near your living place, you can call them and they will arrive at your house to do the job immediately. If this installer is too far away, you will have to worry about how long the job can be done or questions of this sort. Also, if these firms are around you, you can also save money and won’t cause too much trouble.
5. Commercial rooftop looks more feasible.
Since its cost is relatively higher than your expectation, it is likely the system is to be installed on commercial rooftops, for these owners often have enough financial support. Today more and more factories or companies wish to go solar because they want to save money and make a contribution to environmental protection and prevent global warming. This will affect the residential market become of fierce competition.
6. Mass production makes the industry even cheaper.
As more and more people turn to home solar, more solar products including solar modules and inverters will be in high demand. As technology improves, cheaper solar products can be anticipated. For home solar, as products’ prices increasingly go down, people will have enough money to build such a system at home.
7. Education influences people’s choice of home solar.
Although the media have reported all kinds of effects of air pollution and global warming that are surely to harm our lives, how many people really care about it and make contributions to it? Going solar at home is one way to solving this serious problem, but still many don’t know about it or just ignore it. In Europe and North America this situation is much better, while in China and India this seems to be a very big problem. This needs improvement.
