Solar How To Power Systems: How To Determine The Proper Size

One of the most vital steps in the set up of a solar how to power system is determining the appropriate size of the required components. Many do-it-yourselfers have enough solar how to information to accomplish this task without any assistance. But for remote systems (systems completely off the utility grid) or critical applications extensive analysis is required and therefore the advice of a professional is suggested.

The sunlight levels received and the daily power consumptions are the two main considerations used in determining the needed size of a solar power unit. The best orientation to maximize the benefits for a solar how to system is at the true solar south.

This position can be easily be determined by dividing the span of time between the sunrise and sunset in half. The position of the sun at the resulting time is the true solar south.

The insulation is simply the sunlight intensity measured in equivalent full sun. This is equal to approximately 1000 watts per square meter at high noon in most locations. Two factors must be considered in determining insulation: the reflection due to a high in relationship to the solar array and the amount of the atmosphere that the light is traveling through.

In the United States the insulation measurement is highest during June to July and lowest during December and January. All measurements must be considered over a period of time and averaged in order to accurately determine the appropriate component sizes.

Any shade can drastically reduce the output of a solar how to system. Therefore it is always suggested that the units be completely free from shade or at a minimum the spot should be clear from about 10am to 2pm.

It is strongly recommended that the nominal DC voltage requirements be determined up front. This solar how to data will insure that the solar power system can efficiently meet the demands required of it. The information needed can be acquired by contacting your utility company and requesting the details of your power usage. Another option is to use a power meter which can accurately calculate all AC loads.

A major component in the solar power system is the battery. Battery sizes are measured in amp hours. In other words, amp hours are the measure of the battery capacity. This is actually a measurement of the amount of amps of flow or which can be provided over a one hour period. The nominal output of all lead-acid batteries is two volts.

Inverters, which convert DC to AC electricity, are rated according to the watts they can continuously power. Surge watts refer to how much power the inverter can support for a very brief period of time. This measurement is important because some actions require an amount of power that is much higher than the normal amount needed. This would include things such as starting a motor of some sort.

In order to determine the appropriate inverter size the wattage of the items that will potentially operate at the same time must be added. It is critical that this calculation be as accurate as possible. Because the inverter is responsible for the conversion from DC to AC electricity appropriate sizing is essential to achieving desired results.

Items that require 220 or 240 volts will require the installment of a step-up transformer or a stacked interface of two inverters. Transformers are used to increase or step up AC voltage.

If year-round reliability is to be achieved then calculations using the most extreme figures should be used to assess the solar array sizing. The array refers to the grouping of the photovoltaic modules that are connected together.

By gathering accurate information and making careful calculations up front the proper sizing of a solar how to power system can easily be assessed. Calculating the required output needed to power various items will help to determine the size of the specific components.

Determining the actual solar south will assist with the appropriate placement of the system. Keeping the panels clean is another consideration as well. If the panels are tilted at 45 degrees or more they are likely to receive an occasional cleaning from rain and wind. But if the panels are flat mounted over time dirt will accumulate.

By learning all the solar power how to tips and strategies homeowners can more easily get the exact result they are seeking. Through careful and precise planning their calculations will result in an efficient system that functions to provide the power needed.
