It is already a known fact that the initial costs of installing solar panels is high, this reason is the only barrier that keeps people from changing into a more environment friendly source of energy.  However, there are ways in minimizing solar panel installation cost like using thin film modules which are cheaper compared to the conventional solar panels. These include the rigid thin film modules and the flexible thin film modules that are now commercially produced to replace the expensive conventional solar panels produced before. Mass production of thin film solar panels highly decreases solar panel installation cost.

When determining whether solar panel installation can be cost effective in the long run, a person should consider three factors; the kilowatts used at home, the appliances used and the local prices of solar panels. The first factor which should be considered is the amount of kilowatt used at home, this will tell how many panels and how much energy should the panels produce. This can be determined by analyzing the electricity bills in the whole year. Get the highest bill and divide the costs into 30 days which will tell the maximum amount of energy used per day. Therefore with that information, a person can know the amount of energy he has to produce using solar panels.

Second, the appliances used. A typical house contains a refrigerator, at least one TV, radio, heater, air-conditioner and a computer. When deciding to use a solar panel, it is better to reduce energy consumption to minimize solar panel installation costs. The third factor to consider is the local price of solar panels in the market. Generally, solar panels are cheaper in hotter countries than in cold countries because hotter countries have longer daylight and can optimize the use of solar panels. With this, the demand and competition is higher therefore the price is lower. However this is not to say that cold countries should not use solar panels, in fact those who like to use solar panels in their homes even in cold countries, can also minimize the costs of installing solar panels by installing the panels themselves. Also they can buy used solar panels and assemble it themselves to lower the costs. They can also used packaged solar panel kits that are cheaper compared to the pre-assembled ones. Also buy only from reputable sources.

In the long run, solar panel installation costs and the energy it produced will be cheaper. The investment returns can be realized as early as five years up to ten years, and solar panels have a life span of 25 years which means that the extra 15 to 10 year returns are just profit. Aside from money and income, solar panel installation helps lessen carbon footprint. It is renewable and has no negative side effects, it does not release any kind of toxic or pollutant that may harm the environment and it is the best way to adapt to climate change. Using solar panels does not only affect the present but also the future.
