Calculate Your Power Load
Before getting to the solar installation task, it is crucial to sum up the power that you use at your home. This isnt rocket science. All you have to do is to note down the home appliances that you use on a daily basis, which include television, lights, fan, and so on. Next, add the time for which these appliances run in a day. Go through the specification chart in your household electric appliances to check their usage duration or run time, and their power rating.
Now calculate the Watt-Hour by multiplying the runtime of an appliance with its power rating. Follow this step for each electrical device, then sum up the individual watt-hour numbers to get the grand total. You can also simplify this calculation by using an online off-grid load calculator.

If you are sourcing your own quotes, weed bad installers out by:
- Checking multiple review websites. Some reviews websites are easier to game than others.
- Look at the 1-star reviews. These tell you a lot about the true culture of the company. All companies make mistakes but some companies make lots of really bad mistakes. Avoid them.
- Looking for consistency in ratings across Facebook, Google, SolarQuotes and other review sites. Look for a difference of less than 0.2 stars on their average ranking. Inconsistent average scores is a red flag they are gaming one site.

Solar Panel System Tips And Tricks
Oh boy, there is a lot they arent telling you! For example, one really good thing is that these systems are mostly guaranteed for 25 years! What isnt really talked about is that its the solar panels that are warrantied for that long, but the inverters are not. So when youre doing your ROI calculations you need to include the fact that youre going to have to spend thousands of dollars somewhere in the middle of the lifecycle for changing out parts.
In my case, the Sunny Boy 8000 will probably last 10-15 years, and a new one currently costs around $3,000 installed.
Speaking of the Sunny Boy, I should explain that the reason you need an inverter is that the solar panels put out DC current. This is like the current that comes out of a battery. But houses use AC current. So the inverter takes care of the conversion. There are two different kinds of inverters that are currently in use.
Repair Or Modify The Roof If Necessary
Based on your convenience, and the available options, it is possible to improve on the condition of a roof, to suit the need of your solar panels.
If the roof is unstable or faulty, a repair can be carried out by changing the affected parts. For an uneven surface, the underlying framework and surface covering can be modified.

Can I Get A Solar Panel System
Before I decided to get a solar array I had no idea it was such a big deal. But there were a number of things that had to be expertly evaluated before we could even contact an Auckland roof replacement service to put panels on my roof.
First, they had to come out and do a site survey. A engineer had to actually climb up on my roof, take measurements, inspect to see if we have visibility to the south, and use this funky solar pathfinder device to determine the times of day that particular areas would be shaded.
I went up on the roof with him and learned how this worked. It was actually really cool. He went to the four corners of where the solar array was going to be installed with the Solar Pathfinder, and with it point towards the south it has a series of marks on it and a glass dome which reflects anything that would be throwing a shadow. You basically look at the reflection and see what time of day the shadow might affect that spot. 21st century is the time of modern technology. We save seen so many old things changed to completely newer one. E-Cigarette is the best example of that. Firefly 2 recently released vaporizer.

S For Solar Panel Installation
Before getting into how to install solar panels, there are a couple of caveats to keep in mind. First, installing solar panels requires intimate knowledge of solar technology, as well as basic skills in electrical work and in engineering. In other words, you’ll likely want to avoid DIY solar panel installation and leave the process to professional local installers.
The second thing to consider is that solar panel installation won’t happen overnight. After you buy solar panels, there are a few steps in the installation process, and each one is essential for ensuring a reliable renewable energy system.
Determine The Kind Of Grid Connection To Be Used
Net-metering is the most common form of grid connection used in most solar-powered buildings when also connected to the grid.
In net-metering, the solar system is connected in such a way that excess electricity is sent back to the grid. This excess electricity is usually compensated for in terms of the cost, as its value is then subtracted from the bill for power from the grid. Such connections are achieved using a bi-directional meter
In other cases, the solar system is connected so as to supplement the electricity from the grid, without any direct interaction between the two . This arrangement is less economical.

Can A House Run On Solar Power Alone
Practically, it is not often possible. This is because solar only works when the sun is shining – which means when it is cloudy or nighttime, they do not generate electricity. There are some battery solutions to provide power during these times, but they still tend to be quite expensive. Most homes with solar panels still rely on the grid from time to time.
Don’t Miss: What Is Solar Energy Panels
Select And Charge The Battery
A major hiccup with solar power is that it doesnt provide electricity when the sun goes down. However, you can easily crack this problem by using a battery. A lead-acid or a lithium-ion battery stores solar power generated during the daytime and discharges it at night. This provides a steady supply of energy, provided you have selected the optimum battery storage capacity. You will need a power controller to monitor your batterys charging. These come between the panels and the battery. Such controllers are typically fitted with a small LED light that announces the charging state of the battery, and it adjusts the power that flows into the battery.
Inverter And Battery Stand
I made the above inverter and battery stand by the help of a carpenter. The design idea I got from this instructable. The design is really helpful for me.
At the backside, I made a big circular hole just behind the inverter fan for fresh air suction from outside. Later I covered the hole by using plastic wire mesh. Few small holes are also made for inserting the wires from solar panel, charge controller and inverter to the battery and ac output to the appliances. At both sides panel, 3 horizontal holes are provided for sufficient ventilation. A glass window is provided at the front side to view the different led indications in the inverter.
In the inclined plane of the inverter stand, I have mounted the charge controller. In the future, I will install my own made energy meter also.

What Are The Types Of Solar Power Systems
There are three main types of solar power systems:
- Grid-tied systems: The most popular solar system type the home is connected to the grid so it can use electricity from the utility when the solar panels arent producing enough energy to power the home
- Hybrid systems: Also called solar-plus-storage systems the solar panels are paired with a solar battery to store energy for the home to use later on or during a power outage, and the home is also connected to the grid
- Off-grid systems: There is no connection to the grid and the home runs entirely off of energy generated and stored on site

Gear Required For Off
The essential components of an off-grid system are similar to a grid-tie setup with the addition of:
- Charge controller
- Battery bank
- Balance of system components

Assess Your Options For Using Solar
Purchasing and installing a system that you fully own and maintain is no longer the only option if you want to go solar. Even if you rent your home or don’t want to purchase a rooftop system, there are many programs will enable you to still benefit from solar electricity.
Below are some of the options available for using solar energy at home check with local installers and your utility for programs available in your area.
Purchasing a Solar Energy System
Purchasing a solar energy system with cash or a loan is the best option when you want to maximize the financial benefits of installing solar panels, take advantage of tax credits, and increase the market value of your home, and a solarize program is unavailable or impractical.
The solar installer will connect the system to the grid, and receive an interconnection permit from the utility. When the PV system generates more power than the homeowner requires, the customer is often able to sell excess electricity to the grid, and when the homeowners electricity needs exceeds the capacity of the system, the home draws energy from the grid as usual. Learn more about grid-connected home energy systems.
Purchasing a solar energy system is a good option if one or more of the following apply to you:
Community or Shared Solar

What Are Solar Batteries How Much Do They Cost
Solar batteries store your excess solar energy so you can use it when you need it most, like during a power outage.
Most home solar batteries cost between $10,000 and $15,000 to install, so they add a substantial amount to the total cost of a solar installation. However, in a number of states, there are specific rebates to cut the cost of adding batteries to your solar system. It is also worth noting that the 26% federal solar investment tax credit applies to batteries when they are installed to store solar energy generated by a home solar system. This further reduces the cost significantly.
Despite the high price tag, solar batteries are cheaper and more popular than ever before as more homeowners want to protect themselves from widespread power outages. In fact, around 70% of people that use our website to request quotes from local solar companies ask for battery storage. This number is up from less than 50% only two years ago. Blackouts are becoming more common throughout the U.S., and what better way to keep your lights on than a solar battery?

Ordering Equipment: Choosing The Panels And Inverters And Getting Your Installation Scheduled
Now that youre set up with the proper paperwork, your installer will be ready to place an equipment order through their primary distributor. At this point, you will have already decided on the equipment your system will include that decision occurs before the contract sign.
However, if youre looking for advice on equipment selection, here are some things to consider. The two primary components youll need to evaluate for your system are solar panels and inverters. Your installer will likely recommend a particular brand for each, and will additionally offer a few alternatives. Durability, efficiency and aesthetics are the primary factors most homeowners will use to compare the various brands .
To be certain that youve chosen the right equipment for your system, spend some time researching microinverters vs. string inverters vs. power optimizers and look into the best-rated solar panels on the market. Evaluating your equipment options can help you feel prepared for the ordering and shipment stage of the installation process.
Once the equipment ordering process is complete, your property is added to your installers queue.Your equipment will likely arrive on the day of your installation, which can happen whenever your paperwork is approved . Time until install also depends on how many projects your installer has in their queue. If possible, try to get your solar installation done in the winter when solar companies arent as busy.
