How to calculate solar panel requirements?


 If you are thinking about solar panel Installation, it is necessary to consult with a professional solar installer. Many brands offer free engineer site visit services. And as we know, how greatly free services are efficient.

Some brands offer appreciable solar solutions, but I recommend Loom solar engineer site visit services (after participating in their site visit service). On behalf of my presence at the site visit, I will provide you with close estimations related to your solar panel requirements.

To calculate your solar panel requirements, you need to follow these steps:

1.   Find your Peak Load: The maximum load consumed by numerous electrical appliances at a time.

2.   Calculate AEC (Average Energy Consumption) per year: By analyzing your previous three years or recent annual electricity bill, you will calculate your AEC (* This technique is based on local grid supply, not for external sources like Generators).

3.   Find the average PSH (Peak sunshine hours): Analysis of 12-month data of peak sunshine hours in your area can find the avg PSH(=1000w/m2).

4.   Select the area of Installation: The selection of a suitable installation area plays a significant role in the performance of the solar panels. It needs proper research to find the right spot. And research may include the following factors:

·   Maximum sunlight reaches the site.

·   Angle and structure of solar panels.

·   Energy loss by heat or shadows from the surroundings.

·   Dimension of solar arrays and Installation area requirement.

1.   Determine the power rating of solar panels: The rating of Solar panel varies from 0.001 KW to 0.5 KW.



Let's find Solar panels requirement, For example:

If we have,

1.   Maximum load=2.4kW

2.   Average Energy Consumption (AEC) Per year= 4.4 MWh (4,380 kWh) or 12 units per day

3.   Avg. Peak sunshine hours (PSH)= 5 hours

4.   Power Rating = 0.45KW or 450W

5.   Solar array size= Unit per day/ PSH = 12kWh/5h =2.4 kW +10% (to eliminate energy loss) = 2.64kW

By using the below formula, you can calculate solar panel requirements:

Solar array size(2.64kW)/ Power rating of solar panels(0.45kW) =5.86

The no. of solar panels can't be in fractions, so you need 6 Solar panels with a power rating of 450W for the given specification.

It is a paper report, so there is a possibility of different results in practical life. That is the reason to concern Loom Solar engineer site visit services to get the solar panel according to your requirement and individual purpose.

Is the electricity bill less after installing a solar system?

Image
  Loom Solar Many homeowners are interested in installing solar systems for their homes to reduce their electricity bills and their carbon footprint. But how much can you save with solar? And is it worth the upfront cost? The answer depends on several factors, such as the size and efficiency of your solar system, the amount of sunlight you receive, the electricity rates in your area, and the incentives and rebates available to you. Loom Solar In general, solar systems for the home can significantly lower your electricity bill, especially if you choose an  on-grid solar system  that allows you to sell excess power back to the grid. On-grid solar systems are connected to the public utility grid and use a net metering system that tracks how much electricity you generate and consume. When your solar system produces more power than you need, you can export it to the grid and receive credits that offset your future bills. When your solar system produces less power than you need...
