How to install and maintain your PV system?

How do install a home PV system? This is a question always asked and concerned about by those who wish to go solar. But others think this is not a big issue because installers will help you solve the problem. My answer is you had better learn something about it.

First, you should make your self clear that your community permits this. I have heard that some communities don’t approve this. So, making sure of this will save lots of your energy.

Second, before the solar panels are transported to your home, you need a slant rooftop with an area of at least 30 square meters. The rooftop had better be a slope with a certain angle, for this is the best for absorbing sunlight. If you don’t have such a rooftop but only a flat one, you need racks to support your solar panels with such an angle. Or if you don’t think installing panels on your rooftop is possible, you can also ask the installer to install them on the ground to which you own the property right.

Third, when your panels arrive, you may pick out a spot on your rooftop or ground to install them properly. No matter whether you install them on your roof or on the ground, you should make sure they face south, east or west, so that they can catch the most sunlight and generate the most direct current.

Fourth, install some racks on your roof or on the ground to fasten solar panels. After this process you can install the panels on them in the angles that suit your local latitude condition the most.

After the installation, you may connect your panels to the solar inverter or microinverters for the sake of converting direct current into alternating current. Finally, connect your whole PV system to the local utility grid. If you are intended to do so, you may also need to install the prepared batteries into the system to satisfy the constant power supply for your house. Some who have enough financial support can connect to the grid and install batteries.

Once the installation job is over, you must be considering how to maintain it. To be honest, such a system doesn’t need too much of your time for its maintenance. You only need to make sure the panels are always clean, without anything like bird droppings, dust or snow on them. Three or four times of cleaning in a year is enough, unless you meet special extreme conditions. In addition, make sure your solar inverters are free from dust and moisture.

India to Create 1 Million Jobs and Boost PV Inverter Market by Solar Ambition

India has been in unfavorable conditions until recently when its moves become inspirational as it targets to create miracles in the solar energy industry. As Modi took office, all kinds of projects about solar power have been put into practice or are being practiced. Recently news reports from the country have announced that India has set up a solar energy ambition of getting 100 GW of solar energy by 2022. More astonishingly, it is estimated that the goal will create 1 million job positions in India.

In the country many areas are out of reach for the national utility grids, and so these areas have been living in the dark. If some large-scale solar power projects can be built in the country, numerous families having no access to electricity will be able to rid of blackouts at night. On the other hand, when these projects are to be built across the country, human labor will be needed, and so jobs will be created. In detail, the jobs mainly come from project planning, construction, installation and operations.

By setting such a goal, India will not only create 1 million jobs to power the country’s economy and root out its high unemployment rate, but also it will boost the PV inverter market in the coming years. The basic knowledge is solar power doesn’t generate itself, it needs solar panels to convert sunlight into direct current and then PV invters to turn direct current to alternating current, which sustains each family’s power needs. In this process large numbers of PV inverters will be manufactured to do the converting job along with innumerable solar panels.

Currently there are two different situations found in the inverter market in India. One is these photovoltaic inverters will only be used in solar power plants. If so, string, single phase and three phase inverters will be produced to meet the needs. Simultaneously, other types of inverters specially made for these factories must be made. This is the majority of the total inverter market share. The other half share is manufacturers inside the country should also produce microinverters, which are the new invention in recent years. Their specialty lies in that they are only suitable for home power systems. By using these inverters, more electricity will be generated. This requires large sums of money of investment, which most Indian civilians cannot bear at all. Today, the quota for this part is very small but serves as the other half.

In addition, the media report that India hopes to make contributions to climate change by boosting its solar power. The typical example is that Modi and Obama have solidified their common commitment to fighting against climate change.
