Solar Power Systems For Home Use Should Pay Attention to The Type Of Electrical Appliances

Written by Sarah Hwong , Jan 18,2016


Solar power systems for home use is according to the user's actual electricity to design and configuration, including the use of power and electrical appliances. For a complete set of solar power generator system, generating capacity is limited, with electrical appliance also have a maximum power limited. If you inattention that there will greatly reduce the service life of the system, even directly cause damage for the key components.

 First , The using electrical appliance power
After using solar power system, it is necessary to get into a good habit to looking at electric power use. Our product operation instructions will inform users the number watts of the maximum load for system, this is the inverter maximum wattage, users should be aware of it. In Generally, Electric appliances will have power parameter identification, before using , had better to particularly care about the power number , to see whether it is used within the allowed range. If the appliance power is too high, it should not be forced to use.

Second, Electrical appliance type

This is very few people to pay attention , but it need to be care about if you use solar power system. Usually it can be divided into resistive and inductive, resistive electrical didn’t impulse current when using, such as incandescent lighting, electronic energy-saving lamps, electric irons, electric water heater, etc.. However , inductive electrical appliances in the startup has a strong impulse current, impact current often more than the normal operating current of 5 - 10 times, such as fluorescent lamps, television, motor, refrigerator, electric stove, water pump and so on. For example, if the inverter of solar generator kit is 1000W, can drive 1000W electric water heater, but do not drive 1000W motor.

 Therefore, when you purchase solar generator kit, first of all to consider that use electrical appliance power and type, this design is accord with the practical use of the generating system. How to calculate the capacity of solar power systems for home use? Except for the professional can calculation, we can also be with the aid of software estimation.

The cost of home solar generator system is too high to affordable

Installed a solar panels on the roof of our house, this home solar generator system is becoming the renewable energy solutions which have a prospect market. However, for the present  general public, to buy a home solar power system is very difficult as like a marrying pretty girl.

Nowadays, human beings are facing with the problem of energy crises, particularly in remote areas of many countries ,which have restrictions on the use of household electricity, frequent power outage is a very common thing. while for the power grids of the citizen, rising electricity charge also has become a big problem. Now thanks to advances in solar technology, people can use home solar power system to power-up . That could be a good thing for us. but the higher cost installation of solar panels has become a problem,too. The current situation is: home solar power system for the general public is too costly.

At present, the main reason of solar generator kit high cost installation is the solar panel modules which price are too high. As someone said, monthly electronic bills have already too high, so want to install a home solar generator system on the roof. Whereas , when knew the needed installation cost, he have found that could not pay for it. That is to say, for a general family, to install that system is not cost-effective.

Maybe you will say, the government should take a subsidy policy for the purchasing solar panel modules families. There is nothing wrong with it, many countries have done that. But we need to know only depends on the government support is not enough, especially in the difficulty economic period. In fact, all we hope that the researchers keep trying to improve the solar technology.

Use the technology to reduce the cost of solar panels. Only in this way, home solar generator system can be able to become a people affordable renewable energy solutions. Solar power system will Improve efficiency of energy utilization.

How much solar generator system is suitable for own use ?

For  solar generator system, the capacity  is not standard, minimum can be 5W and 10W of miniature solar lighting system, the maximum can reach tens of megawatts even GW ultra large-scale solar power station. If simply ask a family need to install how much solar generator systems, there are no clear answer. because each family's power are not the same, the solar power system is according to the user's actual power to design and configuration.

Firstly, our country has an vast territory, different places have different lighting conditions, which directly determines the system's generating capacity. The same size of solar generator system have a big generating capacity in different places.

Secondly , each household electrical appliances category, quantity and electricity consumption are not the same, some families only use for lighting and a small electromotor, some have two or three TVs, refrigerators and other appliances; some household consumption is less, some are larger, which all determined that how much the size of the system capacity.

Last, the power –on time is also different. Some families are shorter use, some request keep 3-5 rainy days used. These have been decided the system capacity. Besides , users required function are different, too. Some only need to solve the lighting, the simple solar lighting system will be OK. But most families still want these solar power systems to provide electric for ordinary household appliances.

Of course, bigger installation capacity could be better, but also will be more elements. From two point of view of economic benefits and practical, need to design and configuration the solar generator system to be suitable for our power electricity consumption satiation. If you want to make sure how much system more suitable, need to clearly know as following question:

1. Where is the solar generator kit used?

2.Which are the specific appliances or what is the total load ? ( the sum of all kinds of electric power)
3.How many rainy days can be used ?
