As energy prices continue to rise, more homeowners are considering purchasing stand-alone solar systems. In this article, I will discuss the stand-alone solar system price and the reasons for its cost. Stand-alone solar systems work off of one or more solar cells mounted on a flexible substrate. Solar cells are made of many different materials including silicon, indium, gallium and bromide, indium being the most expensive. Stand-alone solar systems work by creating energy from sunlight by using it as an absorber to power a series of solar cells. An inverter then converts the DC energy into AC energy so you can use your appliances.


The first step to determining the cost of the stand-alone solar system is determining your energy load profile. This can be calculated by using the actual energy consumption for your home divided by estimated standby hours. For instance, if your system consumes 1500 watts or more per day, your stand-alone solar system load profile will be high (and your electricity bill will reflect this). Therefore, the cost of the system will be higher.

Next, determine your stand-alone solar system’s energy output. Energy output can be calculated by multiplying the wattage output of each solar panel by the number of panels required to provide your desired output. If you want to use solar panels power systems panels to supply backup electricity to your home, divide the total watts used by the number of days in a year you plan to use solar power. This number is your annual energy output rating and needs to be considered when choosing a solar panel and a compatible standby utility.

Now that you know your stand-alone solar system’s energy load profile and stand-alone solar system components, it’s time to estimate your stand-by energy usage. To do this, multiply the annual energy output rating by the number of days in a year you plan to use the stand-alone system and the annual average energy consumption for the entire household. This number will give you an idea of your standby energy usage. Note that this number does not include your home’s electric consumption, which is always figured into your utility’s rating for stand-alone power systems panels. This number, however, should be as close to your estimated energy usage as possible because it will greatly affect your premiums. You can learn more about your standby energy usage in your online stand-by energy policy or stand-by power system policy.

Energy Storage

One thing you want to look at closely when it comes to stand-alone solar systems and stand-by energy is the amount of energy storage you’ll need. If you have a lot of solar power storage then you stand to save a lot of money. For example, having multiple batteries for storing solar power, such as lead-acid batteries, is a great way to lower your premiums. The higher your storage capacities, the lower your energy bills will be. And with the proper battery storage set-up, your batteries won’t ever run down and you’ll never need to worry about having dead cells in your system.

You can get batteries at different prices. However, you need to realize that even the best batteries on the market today are extremely expensive. Therefore, unless you’re already a solar panel manufacturer or have access to cheap batteries, then you may want to go with the cheapest you can find. While it may be cheaper upfront to buy the cheaper ones, you may end up regretting your decision later because these batteries simply won’t hold a charge over time.

An alternative to purchasing cheap but dangerous lead-acid batteries is to go with a grid-tied solar power supply. A grid-tied system can help you cut your costs and make it easier for you to use a completely green power supply. You basically “turn your own” electricity into electricity that you use for your home. This type of system is more expensive up front, but you can recoup most of your investment by selling back your excess power to the electric company. However, if you choose this route, you must be sure that your system is powerful enough to handle your needs.

It’s also important that you choose a stand-alone system size that matches your daily electricity usage. If you have a lot of household appliances, you may want to consider a bigger system. On the other hand, if you only have a few small appliances, you don’t need a huge system. The larger your system size, the more expensive it will be. Therefore, once you’ve decided on the size of your system, you should also determine how much power you’ll need from your batteries.
