Renogy 100 Watt Solar Panel – Competitors

Renogy Solar Panel Review – Materials & Construction

Word of caution, this panel DOES NOT COME WITH MOUNTING HARDWARE. This is a common complaint since they used to provide mounting hardware.

You will only get the panel.

This video provides direction on the basic components you will need. You can also check out the Q&A section below.

Frame

Like many other solar panels, Renogy’s frame is made from corrosion-resistant aluminum.

The back of the frame has numerous pre-drilled holes providing options when mounting the panel.

Junction Box

The junction box is IP65 rated, making it dust and water-resistant.

Bypass diodes are used, which are supposed to reduce power drops in shady situations. This makes the panels more efficient in shady situations, but reviews are mixed in these situations.

These diodes mean that even without a charge controller, your panels should not discharge your batteries.

Output Cables

The 14 AWG cables that come with the panels are only two feet long, so you will probably need to purchase additional cables.

The cables have IP67 rated waterproof connectors.

Panel Glass

The panels use anti-reflective, tempered glass and are impact resistant.

The panels are also durable and made to withstand heavy winds (2400Pa) and snow loads (5400Pa).

Renogy Solar Panel Review – Performance

Renogy panels are noted for their performance and efficiency, and in ideal conditions, some users have reported generating over 100 watts.

Ideally, you should test your panel as soon as you receive it since there are often time limits on the warranty.

You can get power readings from a solar charge controller or use a digital multi-meter.

Review this tutorial on measuring the power output of your panels.

Renogy Solar Panel Review – Service & Warranty

Service is where Renogy appears to fall short. There have been numerous reports that customer service is hard to reach if you can reach them at all.

There is of course positive service feedback, but this is far less than the negative, unfortunately.

Returns

Renogy offers a “30-Day No-Hassle Returns” policy on their website, but I really don’t know what this means since they offer no additional information.

Based on feedback from consumers, getting in touch with Renogy and returning products is difficult.

Warranty

Unlike many competitors, Renogy offers an easy-to-locate Warranty on their website that is easily downloaded.

The warranty is pretty standard, and below are a few highlights for the 100W solar panel.

  • 25 Year Power Output – 5/10/25 Years = 95%/85%/80%
  • 5 Year Materials and Workmanship
  • If the warrantor’s technical team determines there are “substantial defects” they will repair or replace with new or refurbished PV module.
  • You have 30 days to file a claim from the time of receipt for damages or missing parts.
  • All purchases over $200 require a signature.
  • Original purchasing documentation is required – receipt
  • If panel was purchased from a distributor in the US, and the panel has to be shipped out of the US for repairs, the purchaser is responsible for additional shipping costs.
  • Warranty requests have to be in writing and include the original invoice and written description of the issue.
  • You will be provided an RMA number, and must return the panel or part within 15 days of receipt of the RMA number.

Renogy Solar Panel Reminders

Don’t forget…

  • Open your panel(s) as soon as you receive them and make sure they are not damaged and have all parts. You have 30 days to do this.
  • NO mounting hardware is included with the Renogy 100W (Compact Design Panel).

Questions & Answers

How long will it take my 100W Panel to charge my 100Ah battery?

Time to charge = (Battery Voltage x Battery Ah )/ Solar Panel Watts
If you have a 100 AH battery, theoretically, with the sun shining directly on your panels, it will take (12x100)/100 hrs = 12hrs.
Because the sun is not always going to be directly overhead, and due to other inefficiencies, multiply the result by 2 or 2.5. This means that it will take about 24 – 30 hrs of direct sunlight to completely charge a fully depleted 100Ah battery. If we estimate 5 – 6 hours of sunlight in a day, we can expect this solar panel to charge your 100Ah battery in 5 – 6 days. Therefore, you will need 4 of these panels to charge your 100AH battery in one day.

What Will I Need for Installation?

Extension cables, Solar Charge Controller, MC4 Removal Tool, Mounting Hardware – It really depends on how you use your panels, but these are the basics. You may also consider an inverter, battery, etc.

Where Can I Use these Solar Panels

These panels have several uses, and their smaller size and weight make them ideal for tight spaces – Off-Grid Rooftop / Ground MountedResidential / RuralRVs, Trailers, Motorhomes, Caravans, Boats, etc. 12V / 24V battery charging (depending on the wiring method). Part of a Solar Generator

How Often Do I Need to Clean My Solar Panel?

This depends on where you live, but I usually say as needed or when anything is blocking the panels from direct sunlight. I clean mine once a year.

Renogy Solar Panel Review – Final Thoughts

Renogy has many competitors, but for the budget-minded or DIY consumer, it is still one of the most popular panels in its group.

If you are looking for a compact, efficient solar panel that is well-made and new to solar, this is definitely a solar panel to consider.
