Solar is a great alternative.

The 30 watts solar panel charges smaller batteries

The 30 watts solar panel is for low amp charging and to do many off-grid functions. RICH SOLAR distributes these rigid and strong solar modules. 

They call it the RICH SOLAR 30 watts 12 Volt Monocrystalline Solar Panel Module. It is a High-Efficiency Mono module.

The package does not include a charge controller or mounting hardware.

It comes with an IP65 Rated waterproof junction box and a pair of 12AWG cables attached to the solar module. The cables are 24 inches long.

The manufacturer builds the 30 watts solar panel with high-quality tempered glass. They also provide a strong aluminum frame. That provides for high-quality panel rigidity.

One can use these solar panels for many years. You will experience no faults, defects, or operating failures.

It comes with a superb warranty for up to 25 years.

On a sunny day with 7 hours of sunlight in mid-summer, you can bargain for the generation of about 178 Watt.

That is 7 x 30 watt = 210 Watt.

Now you allow for a loss of 15% and you get 210 X 85/100 = 178, 5 Watt

Ignore the 0, 5 and you get a fair 178 Watt.

With this, you can charge a car battery, but it will take very long. It will work better for low ampere systems or to trickle charge a car battery.

The Corrosion-Resistant Aluminum Frame

The sturdy aluminum frame protects the solar panel from high winds and heavy snow loads. As well as other harsh weather conditions

The 30 watts solar panel comes with pre-drilled holes in the frame to ensure ease of installation. The holes are compatible with ground mounts, Z-brackets, pole mounts, and tilt mounts.

The module comes with high transmission anti-reflective tempered coated glass.

It comes with certification to withstand challenging environmental conditions.

Advantages

• The solar module comes with 13.4% conversion efficiency. It provides excellent performance in low light conditions. The panels work well during cloudy days and still produce a satisfactory output.


• IP65 rated waterproof junction box.


• IP67 Rated waterproof MC4 connectors.


• Excellent low light performance on cloudy days, mornings, and evenings.


• Easy installation and handling for various applications.


• Compatible with on-grid and off-grid inverters.


• The panels are aesthetically pleasing and do not draw unnecessary attention.


• The module comes with good solid and ready to use leads.


• The 30 watts solar modules are cost-effective.


• The modules are compact and easy to set up, but with enough power.


• These Monocrystalline panels will give you the most efficiency per space.

Disadvantages of the 30 watts solar panel

The only downside is there's no mounting hardware.

Also, you have to buy a charge controller for voltage regulation.

To Mention

Best is to not even let a single small shade hit the solar panel. It has a high negative impact.

When buying delivery is quick and the solar module is easy to use.

Warranty

The 30 watts solar panel comes with 5 years of materials and workmanship warranty.

Also a 25 year’s 80% output power.
