How To Wire A Solar Panel To A Battery
If you are new to the concept of how to wire a solar panel to a battery then I am going to assume that you have already purchased or acquired a solar panel.
One of the first things that you will need to do when installing or constructing a solar panel is to mount it on your roof or on the ground . This is because the angle or tilt of the mounting location will determine how high the suns rays can fall or reach the panel and how much energy can be stored. When mounting your solar panel to a battery, the panel should be mounted at a 45-degree angle to the roof or on the ground.
The reason for this is that the angle will maximize the amount of light that can fall onto the battery that will charge the battery more efficiently.
Is Homemade Solar Power Worth It
In most cases, the answer is no. It’s cheaper and easier to just buy a solar panel and be done with it. If you’re looking for a large solar array to power your entire home, buying factory made panels is going to be the best way to go unless you can get access to free or discounted equipment.
But for small projects or ones where you need more flexibility in panel size, building your own panels can be a great way to save money. Will it be the cheapest method? No, but if you’ve got good equipment and a lot of time on your hands, making solar panels yourself is going to be a fun and educational experience!

Type Of Solar Panel Systems
The type of solar panel system you chose will greatly affect the cost. Grid-tie, grid-tie solar and energy storage, and off-grid solar are all options differ in price. Remember, the best solar panels for your property will fulfill your needs and meet your price point.
Lets break down the primary purpose of each system:
- Grid-tie: You have access to the utility grid. Your primary goal is to save money on your electric bill
- Grid-tie solar and energy storage: You have access to the utility grid and your primary goal is to have backup power when there is an outage.
- Off-grid: You do not have access to the utility grid. Your primary goal is to live where it is not accessible.
Once you identify your goals, you can make a final decision based on price.
If you have access to the grid, you can lower the cost of solar panels by using a grid-tie system. When you choose a grid-tie system with energy storage, you have the potential to save even more. Storing electricity in the grid doesnt cost anything, and you may be able to sell your stored energy . An off-grid system is a significant extra cost.
With an off-grid system, youll need to purchase batteries which represent almost half the cost of an off-grid solar system.
If you have the option, we recommend connecting a grid-tied system. However, off-grid solar will still save you money in the long run if you want to live away from a utility grid.

Examining The Recent Growth Of The Solar Energy Industry
The solar energy industry has experienced unprecedented growth in just the past 10 years. Why? Its all thanks to the Solar Investment Tax Credit a federal policy enacted in 2006 that offers discounts to homeowners, business owners and utility-scale solar generators who want to install solar panels either on their roof or on the ground like a solar farm.1 Since then, the industry has experienced an average annual growth rate of 42% and has created tens of thousands of jobs. In fact, according to the Solar Energy Industries Association:
- More than 100 gigawatts of solar capacity installed across the U.S. as of 2021 which is enough power to light 18.6 million homes.
- More than 230,000 Americans at more than 10,000 companies are employed by the solar industry.
- The cost of solar systems has dropped by more than 70% over the last decade.
- Prices as of Q4 2020 are at their lowest levels in history.7
Even better, as prices decrease for consumers, the quality, durability, and efficiency of PV technology increase. Its the ultimate win-win scenario, and its one that deserves a critical examination so homeowners can be educated on exactly how they can benefit from getting a solar power system installed on their homes.
Cost Of Solar Panel Maintenance
In general, solar systems are designed to run smoothly for decades without requiring much maintenance or upkeep. However, even the best systems require routine solar panel cleaning and checkups as grime, dirt and debris can accumulate over the solar cells.
Any sizable costs associated with malfunctioning panels should be covered by your panels warranty, but its not a bad idea to factor in the costs of a simple few cleanings and occasional maintenance.

How Do You Pay For A Solar Panel Installation
Once you know the cost of solar for your unique project, its time to decide how youll pay for solar. There are three primary ways to finance a solar panel installation: a cash purchase, a solar loan, or a solar lease/power purchase agreement.
Generally, a cash purchase is right for you if youre looking to maximize your savings from solar, you have enough tax liability to take advantage of the solar tax credit, or you have the funds available to pay for a solar panel system upfront.
A solar loan is right for you if you dont want to shell out the amount of cash required to pay for a solar panel system upfront, you still want the most savings on your electricity bills as possible, and you would like to be eligible for all incentives and rebates.
A solar lease or PPA is right for you if you would prefer someone else to monitor and maintain the system, if you arent eligible for tax incentives, or if youd just like to reduce and/or lock-in your monthly electricity bill.

Disadvantages Of Pv Solar Panels
- If going off-grid, the power supply is interrupted by natural event of no energy at night
- Upfront costs are substantial, especially if you need to be responsible for your own energy storage battery costs can easily add thousands of dollars for a basic energy storage option
- Winter months will result in less energy being generated due to the lowered angle facing the sun and fewer daylight hours. Further, typically its the heating energy and not electric that is needed more during winter season.
- Likewise, if PV panels are covered in heavy snow, that will hinder the solar electricity generating process of the system, unless the snow is successfully cleared off.
- Some homeowners may find rooftop panels to be not aesthetically pleasing, or even uncharacteristic to the neighborhood
- Not all homes, locations, and rooftops or roof orientations are suitable for solar
- Manufacturing solar panels creates pollution, as does disposing of the old solar panels
- Not knowing the right time to buy as costs may go down even more or better technology may be due out sooner than anticipated

Msquare Solar Panel Technologies
Msquare Energy have a number of panels approved by the Clean Energy Council in Australia. They are currently only producing a 350W solar panel with plans to produce more models within the year.
The MSEA series feature half-cut solar cells meaning that each of the cells are divided in two which retains that power output but reduces the electrical resistance. The cells are mono-crystalline offering a maximum efficiency of 20.50% which we would characterise as above average.
The panels are 1m by 1.69m meaning they can accommodate residential installations with tighter screw-lines.
Msquare is planning to release their Kangaroo series in 2021 which will feature a better cell efficiency than the MSEA series.
