When it comes to choosing Solar Panel Installation systems, you have to consider many factors like the capacity required, the cost and the efficiency of the system. Installing a PV panel system for your home is a costly affair, so you must take your time.

When you are performing Solar Panel Installation in your home, it is up to you to ensure that the panels meet the standards in your country. If you want to get the solar credits to offset the huge price of installation, the panels need to be certified as per international standards. Your installer must be able to provide the appropriate proof.

Even the inverters that are connected to the grid need to be approved before being connected to the grid. They need to comply with minimum standards and in some countries like Australia they should have the latest Certificate of Suitability. This is especially important because there can be some low-quality imported solar PV panels in the industry.

1. Capacity Required

An average home would consume around 18 kWh of electricity in a day and this rate is growing with time. And, this average consumption can vary from one place to another in the same country. A 1 kW Solar Panel Installation system would produce around 4 kWh of electricity in a day, depending upon your area. This accounts for almost 20% of the electricity consumed by an average household in a day.

So, the larger the PV panel system that you install, the more electricity you would be producing. For example, a 1.5 kW PV system would produce around 2,500 kWh of power every year. This comes to around a third of the electricity consumption of an average household.

2. Warranty

The warranty offered on Solar Panel Installation systems from manufacturers range from 5 years to 25 years. However, you should install a system that has a warranty period of minimum 25 years. Otherwise, you cannot trust the manufacturer.

3. Efficiency

Every manufacturer and supplier uses energy efficiency as a selling point for their Solar Panel Installation systems. However, the fact is that it wouldn’t tell you how the PV panels would perform. However, the more important thing you must consider is the amount of energy that the system would be producing in a year against the money that you spend.

4. Cost

A 1 kWh system would cost you around $10,000 before you claim the rebates and incentives. However, after claiming all the rebates and incentives you can expect to pay something between $6,000 and $7,000. This would significantly depend upon the area were you live. However, there are also some manufacturers that are offering Solar Panel Installation systems for as low as $3,000 after deduction of the government aid.
