The sun above us gives more than enough power that the whole world’s energy power and solar energy will not run out anytime.
Solar energy is renewable and this is environment friendly. Solar power means – the power that generates energy from the sun and converts into electricity.
The terms solar panel can be used for the different applications, such as – telecommunications equipment, remote power systems, and of course in residential areas, as well as, for commercial purposes.
When it comes to the size of cable for solar panels, you should carefully measure the size. This is a little tough task for some people.
But no worries – this guide will explain everything so that you can easily get the proper size for the 12v solar panel.
System for 12v solar panel cable system
For the performance and safety level choosing the right cable size, is very important.
If the wire you choose is undersized then chances are the voltage will be drop through the wires. As a result, this will be the cause of excess power loss.
And if the wire is undersized, this would be very risky that’s because the wires may heat up that could be the reason for the fire.
The following we’ve shared how you can sizing a 12v solar panel. Just follow these simple steps –
- What are the wattages of the appliances you use?
This is the first step on how you can sizing the 12v system. Make a list of the appliances you use throughout the day, also, list of the wattage.
When you find out the Amps not the watts, don’t worry – simply multiply the amps by 12 and this will show you the watts of the appliances you use.
- Calculate the daily watts hour
Measure the per watts hour you are going to use per week and then divide this by 7 – this will give you per hour watts.
Just multiply each appliances wattages by the hours you’ll spend in a day and then add the totals – by doing this you will get the daily watts hour.
- Calculate the panel size
Find out the expected hours you are going to use on an average day, then divide the daily watts-hour with the expected hours.
By this, you will get the minimum panel wattage you are going to use.
- Measure the size of the battery
Once you get all the hours watts, now calculate the battery size.
First, create a weekly requirement and for this multiply the daily watts hour by 7 and then divide the result by 12 – this will convert the watts to the amps.
To get the correct battery size, multiply this by two.
- Charge Controller
Now it’s time to size your charge controller, you will need the amps for this. Just divided your panel watts by 16.5 – it will give you the amps produced per day.
Here’s we’ve shared an example so that it would be easier for you to get the exact size for the 12v solar panel.
For instance, you want to run your TV for 3 hours which is 50 watts, plus a 10 watts light for 6 hours.
So your daily watts hours for the TV would be 50 x (3/7)= 21 wh. On the other hand, for the light, you will need 10 x (6/7)= 8 Wh.
Thus your daily requirement is 29 W (21+8).
The solar panel system will be mostly used in summer, you will need a panel that is 29/4= 7 watts or more.
And the battery size would be (29 x 7 x 2)/12 = 34 Ah.
While the charge controller would be at least 7/16.5 = 0.4 – this is the ideal solar input for your solar panel.
This was the method on how you can find the cable for your 12v solar panel. Keep in mind – using the safety wire is very important also, you should be conscious about the length of the wire you choose, voltage, as well as, the costs. That is why make a plan in detail and then buy the cable.
Advantages of solar panel
When it comes to the solar panel, the wind energy cables come in the place that’s because this is growing as the major source for renewable energy.
You can find a wind farm in the USA near the sea and on the land as well.
The wind energy cables help generate mechanical power. And this mechanical power converts into electricity.
Around the world, wind energy cables are the fastest ways to generating power sources.
However, the solar panel has many benefits or advantages – this is one of the great ways of gathering energy direct from the sunlight.
- Renewable Energy Source
The amazing fact about the solar panel is that – the energy can be renewable. Every day the sun gives unlimited power, and do you know, the energy provided by the sun for an hour can meet the global energy for a year?
As long as we have the sun, solar energy will be accessible so solar is a renewable source of energy.
- Energy can be used everywhere
You can deploy solar energy anywhere you want as long as you have the solar panel. Particularly, in the remote area where no access to electricity – in those areas, the solar system would be an ideal option.
- Low Maintenance Costs
Usually, the solar panel doesn’t require maintenance a lot – when it comes to the maintenance, the solar panel needs to be clean, that’s it!
You just need to clean this a couple of times per year, or you can seek help from the specialized cleaning companies.
The solar panel will not wear or tear like standard cables. You can replace the inverter after 5 or 10 years and other parts don’t need to change.
- Reduces Electricity Bills
Solar energy helps to drop your electricity bills. Moreover, you can save much when you have a solar system, also, this helps to save heat usage.
Furthermore, the grid company will pay you back as you can sell the unused electricity back to them. So investing in the solar panel is worth it.
