How to Determine Solar Panels Cost?
The continuous increase in cost of electricity encouraged people to think about alternate source of energy. Due to this, use of solar system is gaining popularity day by day. The solar systems are made to meet the needs of energy for households as well as businesses. You can provide power through solar panel to any household appliances like, washing machines, Television, computer and lights etc. If you are interested to own electricity used in your home or business so environment friendly decision would be solar electrical system for your house and workplace. The solar panels cost would be the first concern before you purchase the one for your home and business.
The solar panel cost is actually a division of following main aspects:
1. Manufacturing cost of solar cells
2. Size of Solar panel
3. Number of inverters
4. Mounting Structure
5. Installation cost of Panel
Solar Cells
This is an important part of your solar system to determine solar panels cost. Amount of energy produced by solar panels is mainly depended on the following factors of solar cells.
Operating time
Quality
Production technology
These three aspects contribute towards the solar panels cost. Care must be taken while selecting between two identical solar cells available in market with different prices. It is usually suggested that you should measure its value by comparing its rate per watt. For example if solar cell produces each watt for $4.30 so solar panel which produces 50 watt, will cost you $215. Broken solar cells in factory are sold at extremely cheap price by the producers that are known as scrap cells. Use of these scrap cells can reduce your overall solar panels cost. However, people experienced in soldering can take benefit from the scrap solar cells.
Size of solar panel
Size you go for will be according to your needs. Need refers to your consumption of energy and your estimated future consumption. Many companies are operating in the market claiming to provide you the best value of your money. Energy efficient solar panels are also found as cost effective as you need to buy few panels in that case.
Number of Inverters
Usually one inverter is enough for the current solar panels available in market however few types of solar panels and strings in it may require you to buy two or more inverters. Therefore, inverters type and size will also contribute to the solar panels cost significantly.
Mounting System
This is an important consideration before installing the solar panels. Your preference and need determine the space required for the solar system. You can place your solar system, either on the roof, or on the ground. This will also decide the solar panels cost as well. If a structure is required to build especially for your solar system then this will surely increase the solar panels cost.
Installation cost of Solar Panel
The Solar panels cost highly depends on either you hire the services of a professional installer or do it yourself. Usually a professional costs around $12 per watt. Whereas if you go for installing the whole system by yourself it will reduce the solar panels cost to around $4 per watt. To reduce the installation cost, you can purchase the solar system kit. It includes all the required accessories like inverters, solar panels, batteries, mounting racks, cables and chargers needed to build your own solar system.
Today governments are encouraging its people to convert towards this most economical source of energy. For the purpose, they are providing rebates and other incentives like loans to the people who shift to solar systems for their energy needs. Therefore, conversion to solar system is advantageous for many as it increases the worth of our property and you will be saving money on your utility bills in the long run.
