How Many Batteries Does My Solar System Need?

So, you have decided that you want solar power for homes. You’ve checked out a few solar panels
and visualized what they might look like in or on your house or office … but how can you tell exactly how many solar power panels will you need?

Here’s how to determine exactly how much wattage you’ll need, specifically tailored for your home individually and how to take that info and use it to know precisely how many solar panels you will need. Would that be useful? You know it would!

You have to start by establishing how much energy your home consumes. You cannot know the exact amount of solar power panels that you’ll need until you have accurately made that calculation.

Do this by studying your old utility bills. Establish your monthly average energy usage, ideally over the course of a full year to account of the changes in the seasons. Take note of the total amount of kilowatts per hour (kw/hr) your home consumes.

To get the average kw/hr your home requires, simply divide the total kw/hr by the total number of days in the billing period you’re looking at. Most utility company billing periods are for 30 days.

By doing that you will know how many kw/hr your solar power for homes system will require each day to meet your solar energy needs. If you do this for the whole year, you’ll know both your average daily usage and times in which your consumption is likely going to peak. This is essential information for sizing up how many watts your home needs.

You have to confirm that your electricity company is happy to buy back the extra solar power that your solar power system makes. While it is rare indeed for an electricity company to actually pay you for the extra electricity you supply them, most are happy to buy back power up to the extent of your current bill. After that, they will accept it but only under condition that they won’t actually pay you for it. You need to check out where your local company stands on this matter.

If you are someone who is choosing to not go fully off-grid (which is perfectly reasonable by the way!) and you haven’t invested in any batteries to store the extra solar power, then some days you’ll be selling your solar energy to the utility company. In the U.S., by law electric companies have to pay you whatever rate you would pay them. On other days, you don’t produce enough solar power for homes and you may be buying energy from them. Either way, over the duration of a full year, you want to aim at having your energy bill end up around the zero mark. In other words, you want to have just the right amount of solar power panels, not too many and not to few.

Energy companies rarely (if ever) offer to give you money if you over-supply them. So do not build a solar power for homes system that will produce more solar energy than you could ever possibly use. You want the system to generate just enough to keep your bills at zero.

To establish exactly how many watts of solar power panels you need, you have to work out how many hours of direct sunlight that your solar power for homes system will receive. Effectively, how many hours of direct sunlight does your home soak up on average over the course of the year?

There are several ways to work this out. The ‘hard way’ is to take time daily to notice for how long the sun shines on the part of your roof where you are thinking of installing your solar power panels. Now let’s face it! Because you probably won’t want to keep this up this laborious daily chore for a whole year, this way is almost certainly totally impractical.

If your solar power for homes system has tracking system, (a built in ability to move and track the sun) the number of hours of sunlight your roof receives will not be the same as the number of hours of direct sunlight. Your calculations will be different because the sun’s light hits the solar power panels from many different angles (not only when it’s coming in at right angles to your roof).

Generally speaking, most houses enjoy roughly 5 hours direct sunlight on average throughout the year. This is a rough approximation, so don’t get upset with me if it turns out you get less energy than this article suggested! (You could always return to daily readings if you want!)

If you live in the U.S. and you want to get a far more accurate assessment, look for your local average regional value. In August 2004, the Florida Solar Energy Center presented a study entitled “Geographic Variation in Potential of Rooftop Residential Photovoltaic Electric Power Production in the United States” in which they tested power generation
of a 2 kilowatt solar power for homes system all around the U.S.A. They took readings in more than 200 locations throughout the U.S. The research showed that on average a 2 kw rooftop system would harness between 5 and 8.5 kw/hr per day throughout the year.

So taking the low end of the scale, a 2-kw system would experience 5 hours per day of sunshine. Therefore, that 2-kw system could expect to enjoy 10 kw/hr of solar power per day on average across the period of the whole year.

Consider how you were planning to use the solar power for homes. Were you wanting to go completely off-grid? That will create greater demands on your solar power for homes system. Also, be aware of any potential problems such as tall trees blocking your sunlight to the solar power panels.

If your average power consumption were to be 600 kw/hr per month and you establish that your electricity company has a billing period of 30 days per month, then you can know that your daily energy consumption is 20 kw/hr per day (i.e. 600 kw/hr divided by 30 days per month).

Using the Florida simulation data found in the graphic entitled, “Geographic Variation of PV Power Production Around the U.S.”, we can see for example that the southernmost tip of Florida has an estimated value of 7.5 kw/hr based on the use of a 2kw rooftop PV system. Therefore, we can know that people living in Southern Florida receive an approximate average of 3.5 hours of direct sunlight per day.

If you know your home is currently using 20kw of electricity per day (aka 20,000 watts), then, given that you know you receive an average of 3.5 hours per day of sunlight from which to produce your total solar energy needs, then the solar power for homes system you would need to incorporate roughly 5,700 watts of solar power panels to deliver the amount of energy your home typical consumes everyday.

Build Solar Panels for Your Home Cheap.

Ever opened your electric bill and said “Wow we need to cut back?” Well no you don’t If you leabuild your own cheap solar panels you can easily decrease your electric bill by a massive amount. Take a look below for more information on why you should and how you could switch to solar.
1. What can you expect from your solar panel investment?


1. They last a really long time and are virtually maintenance free. A lot of people don’t realize how cheap and effective this investment can really be. 2. They are extremely cost effective and you can expect them to pay for themselves in just a few months and they have long term payouts. Some people avoid utility bills all together and even generate surplus power that is returned to the grid and receives credit from the utility company or you can use this energy at a later date. A solar panel investment is a good place to start if you are planning tom make your home more energy efficient.

2. What is the cost of solar panels and are they really worth the investment?

There are two ways to make the investment. The smartest and most effective way is to build your own solar panels. It sounds more like a job description than something that the average person can do. But you would be surprised of the simplicity behind constructing your own panels and even doing your own installations. Or you can buy retail versions that can run you several thousands of dollars and could take several years before you see any positive equity from your investment. Building your own solar panels is the cheapest and the overall most practical way to make your investment and it is something that ANYONE can do. All you need is the right step by step instructional guide that will walk you through every step of the conversion to make it as easy as possible by showing you all the affordable ways to get materials, construct, and install your new system for a small fraction of where you’d expect to pay elsewhere.

3. Environmental and financial benefits of using solar panels as an alternative energy source.

The sun puts off enough energy every hour to supply the Earths energy demands for an entire year and it is a natural source of energy that just goes to waste. The solar cells in the panels absorb this energy and convert into electricity that emit no greenhouse gasses or harmful emissions which makes this one of the ultimate alternative energy sources ever. The financial benefits speak for themselves. It really all depends on how far you are willing to take your project. Solar panels can handel a number of individual jobs or one huge massive job and Earth 4 Energy’s step by step guide supplies you the tools and information needed to construct your panels and apply them where necessary and how to optimize them for maximum results.

Solar For Your House: Learn The Lizard Lesson.

Using the power of the sun to provide heat or light in your home can be done a couple of ways. In this article, we look to lizards for a basic solar lesson.

Solar For Your House: Learn The Lizard Lesson

Nature is a funny thing. If we pay close attention to it, we can often find the answer to many questions. Solar is no different. In this case, we are going to look at lizards for guidance.

Undoubtedly, you have seen lizards sunning themselves on rocks if you have ever gone hiking or even just sat outside. If you gave it any thought, you realized the lizard was using solar power to warm itself. It positioned itself to maximize the exposure to the sun by determining where it was going to get the maximum warmth. As odd as it may sound, using the sun to heat your house involves the same approach.

The goal of natural solar heating for a house is to maximize the exposure to the sun throughout the year. The more surface area that is exposed, the more energy you can convert. Get it wrong, and your results will be very disappointing.

If you live in the Northern Hemisphere, the south side of your house will always receive the most sunlight. As a practical matter, this means the longest side of your house should face south. This side should also contain the most windows to convert the energy. While facing south is important, there is an additional step.

The Earth tilts through different degrees throughout the year, one of the factors that gives us seasons. You need to realize this and position your house for the appropriate time of the year. You are probably not going to need heating during the summer. As a result, you should not orient your home to the path of sun during this period of time. Instead, you should determine the path of the sun during the winter, to wit, the angle at which it strikes your property. You will be surprised how much of a difference there is, but will be glad you take it into account since this is when you need to the most heating.

Much like a reptile changes places on a rock throughout the day, you need to gauge the best position for your house to take advantage of the power of the sun.

Learn how to create electricity and save your bills!! Read on how you can make your very own solar panels at your own home!

How to generate free electricity-Magnetic Generator-Solar Panel-Electricity Windmill.

The concept of Free Electricity in households is very hot this period because of the economic recession that many nations go through. People want to cut expenses and the idea of reducing electricity bills for homes by at least 50% is very appealing. Imagine that for a second: Your average monthly electricity bill could be around $200 so saving half of that would mean a total savings per year around $1200 which is a nice sum of money.

There are a few Do-It-Yourself electricity generator plans and guides that you can find on the Internet. They are really helpful as they take you by the hand and show you how to create a “homemade” electricity generator with materials and tools that you can find easily on a DIY store. These generators are mostly based on wind or solar energy. The DIY guides basically show you on video and using graphical plans how to build solar panels and windmill electricity power systems. This means that the generator basically works with either wind or sun light in order to generate electricity from those energy sources. However, what if the place you live does not have a lot of wind or there is not much sun throughout the year?

I have stumbled across a new type of DIY electric generator, the so called “zero point perpetual magnetic generator”. This electricity generator is based on magnetic energy. You basically construct a free-wheel turbine motor which is placed in the middle of strong permanent magnets. The magnets are placed in such a way such that their magnetic field forces the turbine motor to rotate (indefinitely as they claim). The rotation of the turbine motor is what generates the electricity energy.

All of the above green-energy sources are an excellent concept for home use in my opinion. My only doubt is about how much reduction in electricity bills you can achieve. I have my doubts regarding the power efficiency and how much actual electricity you can produce with such systems. If you are a person with good practical skills you can try one of those DIY guides about “generating free electricity” and draw your own conclusions. If your home electrical needs are relatively small, I believe that a “free electricity generator” can reduce your bills by a significant amount. If you however live in a house with high electricity consumption, then don’t bother with such a DIY electrical generator. Check out the following guides about building your own “green electricity” generator for more information.
