How Many Solar Electric Panels Will You Need?

Your Ideal Solar System will include solar electric panels or technically called Photo Voltaic or PV Panels for short. If you have taken steps in saving energy as suggested in the Energy Saving pages of this web site you are ready to estimate your needs for PV Panels for Your Ideal Solar System. If you are an experienced do-it-yourselfer this information can be used as a guide. It is not recommended in most cases because there are professionals in this area that know things you may not be aware of.
There will be two parts to this. The first will be to estimate the maximum power you use in a month. This part will be done by you by looking over at least the last year of your electric bills. The second part will be to estimate "Roughly" the solar power needed to replace your power usage from your electric company.

Your needs will be based on usage of electricty measured in Kwh or Kilo (one thousand) Watts Hours. The information you need is on your electric bills so gather them up and lets take a good look at what they can tell you.

What Will Be Your Estimated Savings?

Your electric bills will show you how much power was used each month so that you can see the highest and lowest energy usage and which months used the most and the least amount of power.

Your solar electric panel requirements will drop considerably if you have in place energy saving light bulbs,water heaters etc. and have taken any steps to reduce wasted energy. To ensure you take full advantage of reducing your energy consumption to the lowest possible without reducing your comfort and lifestyle, get an audit by a certified Building Energy Professional.

If you are planning to use solar water heating you can take around 30% of your estimated usage of electric off of your solar electric panels requirement. An example would be: The year before, your highest monthly usage was 1,000 kwh/month used then you can figure you will be using around 700 kwh/month at your peak level if you install solar water heating.

Looking at your most recent electric bill and seeing the cost per Kwh you can estimate your savings just on the amount of electrical costs saved on using solar water heating. This figure does not yet include tax incentives, rebates and an increase in your home value (for every $1 you save a year on energy costs adds $20 to your home’s value).
Next is to figure your savings if you use solar to provide you with all your electrical needs. In looking at a Florida electric bill there are two basic charges one is for energy the other is for fuel. Together about 12 cents per KWh. So for 700 Kwh maximum usage per month you can estimate a savings of $86.76 for your highest energy usage month. With the cost of energy and fuel increasing on an average of 10% each year , low cost financing and the cost of solar today can help make Your Solar Savings Project Is a Wise Investment.

In the past few years the solar industry has increased each year by an estimate of 60%. Because of this there has been more and more interest and money invested in its improvement and manufacturing. This along with the lowest interest rates for financing, leasing options and the price of energy from your utility company on a constant rise, your investment in solar can make more sense than ever.

Solar Electric Panels - Usage Requirements

If you are looking at implementing your options to get solar electric panels now, then we need to address this in a way that you can get to your bottom line and make the decision to move ahead. So lets start out looking at a list that will help you to address your priorities and needs both now and those of the future.

Average Home Electric Use Percentages -

1. AC/Space Heating----37.5%
2. Water Heating--------30%
3. Appliances-----------17.4%
4. Cooking--------------10.3%
5. Lighting---------------4.8%

This will give you an overview of what your usage in these 5 areas might be. You can choose to get a complete solar system that provides all the electricty you will need now or you can take steps in reducing any unnecessary waste of electricty before installing your solar electric panels.

Alright so let us take a look at your estimates so far and see what you can start with. Assuming you are heating water with solar heating panels lets now take a look at what is left to power with electric panels.

Electric Solar Panels come in many sizes and outputs from 5Kw to 600 Kw. When you start looking at what sizes and power ranges for solar panels you will also need to look at your power usage priorities are. If you are planning on using solar to heat water you would use the following percentages based on averages. Again if your think your usage in one of these areas are more or less adjust the percentage accordingly when doing your calculations.

1. AC/Space Heating-----45%
2. Appliances------------25.2%
3. Cooking---------------17.8%
4. Lighting---------------12%
_______
100%

Let us say for your specific requirements that you use no more than 1,000Kwh in any given month. Set your priorities with the most important first and estimate from there. The limitation of available space for solar panels may determine your total power output and that is why we take a look at your priorities. Even in cases where providing solar power for some of your electrical needs can make sense.

Now that you have a general overview on what your estimated requirements are, you can now estimate the costs of your solar electric panels.
