Q8 How Will I Know If My Property Is A Good Candidate For Solar Panels
Ans: The optimal situation for a solar energy system would be when it is placed in a field facing south with very little hindrance. That means there should be nothing nearby which could cast a shade on the solar panel.
But do not be disheartened if your property does not seem eligible according to the criterias on paper. Because, only a professionally trained solar panel installer can know these things for sure.

Whats Not So Good About The Renogy Flexible Solar Panel
The major complaint with the solar panel is that the positive and negative cables are not the same length. And the cables are generally too short. This is fine for connecting in series right next to each other. For most other types of installation an extension will be required to reach the charge controller.
This is not a portable solar panel and it wasnt designed to be. This kind of panel is meant for fixed installation to vehicles, boats and small structures. I really cant see the point of mounting it on a frame and using it as a portable solution. But because it is so light it could be used for hanging on a larger tent. You would have to be careful when you are transporting it for this specific portable use. Renogy has several solar panels that are designed for portable use. A list of which I give below.

Still, always check your products specifications.
What Is The Renogy Flexible Solar Panel
When traveling or vacationing in recreational vehicles or boats. Electricity is required to charge the batteries. Off grid power has traditionally been generated by fossil-fuels like gasoline. To charge leisure and house batteries it means running the engine. This uses valuable fuel which is becoming more and more expensive. It also means using up fuel that may be required to find a gas station or port.
The noise and constant throbbing can be very irritating and the Co2 release damages the environment. But there is a quiet and clean way to generate electricity by harnessing the power of the sun. Installing solar panels will release you from the constraints of having to run the engine or generator.
Using flexible 100w solar panels will allow you to generate electricity whenever you are out and about or at sea. The solar panels will collect the energy from the sun and allow you to power appliances or charge electronics. This means while the sun shines you will be able to take longer trips without the need to refuel.

They both do a great job, but sometimes MPPT controllers are very cost effective talk to a RENOGY technician to find out how.
Renogy Solar Power System Cost And Warranty
The cost of the system depends on different individual factors. Renogy estimates the average cost to range between $1.73 and $2.05 per watt. Therefore, an average 5kW system may cost around $8,600 before tax rebates.
The tax rebates and credits depend on your location. After tax, the average cost is about $6000 exclusive of the inverters and installation cost. Renogy system offers a 25-year warranty period for transferable power output and five years for material and skill for a maximum system voltage of 600V DC.
With the warranty, the user can claim compensation if the system suddenly stops working or if they experience other issues during those covered years.

Whats Unique About Renogy
Renogy makes a point of building comprehensive kit products for consumers who want to install solar versus just selling systems that are built from various components.
Because of this market approach, Renogys inverters are purposefully matched to their solar panel kits and the homes that they will be installed in.
Consumers dont have to try to figure out how to match compatible items together Renogy does the work for them with the kit that is provided right from the start.
As a result, the company has had great success selling their solar power system products to the average Joe and consumer wanting a kit that involves one complete purchase and installs.
Along the same lines, consumers will find that the Renogy inverter choices are matched to three kit choices: tiny house, cottage package, and village package.
Obviously, the smallest choice is good for a basic hunting cabin or getaway location up in the mountain with a simple lighting system .
On the other hand, higher-level cottage and villa packages are designed for bigger residential needs, providing sufficient power for computers, phones, and small appliances.
These systems are ideal for areas that have intermittent power issues or frequent storm cutoffs where people need power alternatives when the normal grid goes down a lot.
Is A Charge Controller Necessary
Most definitely, yes! Charge controllers are a very important component of part of any solar installation.
The only time you dont really need a solar charge controller is if using a solar panel less than 5 watts.
A solar charge controller connects the solar panels to the battery/batteries, limiting how much charging current flows and how fast your batteries charge. They effectivelt prevent overcharging.
Solar charge controller can prevent batteries discharing too much by disconnecting the system if stored energy goes below 50%. Battery life reduces if regularly discharged more than 50%.

How Does The Renogy Eflex 50 Solar Panel Work
The Renogy 50 watt solar panel is made from 2 x 25w monocrystalline solar panels. The panels are sewn into a polyester canvas frame. They fold in the middle to produce a smaller easily transported package.
E.Flex 50 Watt Specs
Solar panels are made from Photovoltaic cells. These cells react to sunlight and convert its energy into usable Direct Current electricity. The cells are encased in a metal or plastic frame to form the solar panel. There are generally three accepted types of solar panels:
- MonocrystallineAre single solar cells manufactured from the purest silicon. The solar panels are recognizable by their dark colour
- PolycrystallineAre manufactured from multiple crystalline solar cells. The solar panels are recognizable by their blue speckled colour
- Thin-FilmMade by covering a material with one or more thin layers of PV cells. The solar panels are recognizable for their extremely thin and lightweight characteristics.
The Renogy 50 watt portable solar panel houses monocrystalline solar cells. These are the most efficient because the solar panels are made from single PV cells. Its official efficiency rating is given as up to 21% 23%. I suspect it is termed in this way taking account of weather conditions. Still the average efficiency benchmark within the solar industry is 17-19%. Some solar panels are even lower than this. So overall the efficiency rating of the Renogy 50 watt is pretty good.
