If you are going to install your own solar panel system as a renewable energy source for your home, then you want to invest a considerable amount of time in solar panel design.A well designed solar panel system will save you time in the initial installation while saving time, and a good design will save you money in the long run.The key to a good solar panel design is knowing how much power the solar panel system needs.You can evaluate your current energy consumption based on the fees you currently pay to the appliance company, or you can find many calculators on the Internet to provide you with estimates based on the type of appliance you use.If you calculate an unreasonable amount of maintenance with a solar panel system, then you can make a lot of changes to reduce your energy consumption.Changes you may want to make include: using a low wattage bulb, rethinking your heating options, and checking out all the appliances you 've been using, such as refrigerators and stoves.If you are not using an appliance or use it rarely, consider getting rid of it completely and saving yourself trouble.After you determine how much energy you consume in a day, you want to calculate how much solar panel array you need in your solar panel design.Again, there are many online calculators that can help you, and you want to have as many solar panels as you need to achieve the total power consumption per day.If you do not find an online calculator, you can consult a solar professional or check the packaging on the solar panel you intend to purchase and they will point out how much energy they have output.The next consideration for solar panel design is the battery.Before determining the system battery, you need to find the voltage generated by the system.In general, if you have a smaller system, you will want to use a 12 V battery if 24 V is larger.If you are designing an entire office building or telecom then you can consider using a 48 volt battery.The last thing you want to consider is the cable needed to connect the panel, the battery and the inverter.The placement of your solarpanel design Assembly will play an important role in determining what type of cable you need.The further the distance between components, the greater the possibility of energy loss, in which case it is best to invest in high quality or larger cables.Now your design should be more complete and you need to determine the type and size of the inverter you are using.Verify the requirements and possible financial advantages of using the inverter with the local municipality.After paying attention to these details, you should have a relatively good design, and next you want to make sure you understand how to connect the solar system and have your materials ready.There is a little energy in advance and you will give yourself some sadness in the long run.
