Wishlist - What do you need for DIY Solar Energy?

For the Summer of Green Technology, we're focusing on renewable energy, like solar and wind power. In this wishlist, we'll go over some of the components that you might need when putting together your own solar power system. Since there are so many different energy requirements, we won't get into any individual designs - this is more of a general list of parts you might need.

Solar Wishlist Giveaway - Ended

Answer the questions below for a chance to win a Multicomp Pro - Pro Solar Light/Solar Power Meter.

  • What are some tips on integrating renewable energy into your designs?
  • If you have past projects which used renewable energy, we'd love to hear how you did it...and of course, we'd love to see some pictures!

Terms:
Post your answer as a comment below between 8th May 2023 and 16th June 2023. The best answers will be chosen by the element14 community team, and you will be shipped your prize (or local equivalent) free of charge.

Solar Cells/Panels

When selecting solar cells/panels, estimate your energy requirements and calculate how many you need - it might be a lot. For smaller projects, check out the following:

Battery

You can use a 12V lead-acid battery for a low power system, while a high power system may require multiple deep cycle batteries with a total capacity of several kilowatt-hours.

Charge Controller

A charge controller is necessary to regulate the flow of energy between the solar panel and the battery. It prevents overcharging and helps prolong the life of the battery. Choose a charge controller that matches the voltage of your solar panel and battery.

You can also build a charge controller; parts will vary depending on what type you want to build. Here's an example that uses an Arduino: MPPT Charge Controller 

Here are some of the parts you'll need:

Inverter

If you plan to power AC appliances, you will need an inverter to convert the DC power from the battery to AC power that can be used by your appliances. Choose an inverter that matches the voltage and wattage of your battery and appliances.

What if you want to build your own? An Internet search should yield some designs, from simple to very advanced. This link shows a simple inverter circuit; it outputs more of a square wave, but that should work for most applications! Here are some of the parts you'll need.

    For a remote IoT device like data logger or environmental monitoring solar power is very effective if you don't like to replace the battery every few days. An efficient solar charger is required for this…

    In addition to all the good suggestions, a movable solar panel would be useful to optimize the attack angle of each panel to the sun's rays.  Hopefully motorized, but not required.  And just a suggestion, having viewed a number of homes in our area with solar panels installed, make use you check the estimated remaining life of your current roof before the installation.  It can get expensive to remove the panels when replacing your roof tiles, then reinstalling the panels.

    It's hard to tell on an average basis will all the other variations.  I probably ought to try to define a "reference day" to get measurements with the same irradiance and ambient temp and sun angle.  I haven't been that diligent. Probably need to clean the panels first - that's the hardest part...

    The system is a bit over 5 years old and the projected life (warranty if you believe it) should be down 8-10% at year 25.

    Has your solar power reduced as the solar cells age? Or is that hard to determine?

    I have a 4KW roof mounted solar system using a string inverter with two strings of 9 panels each.  What I'd like to try as a DIY project is a semi-portable system of 1 or 2 panels with microinverters.  New technology panels are 400W whereas mine are 285W.  Have not looked into what it would take to run a microinverter off-grid.  Maybe there is already an existing solution.  Something like a modified battery powered UPS with a frequency source.

    For low power MCUs TI MSP430 is still attractive - as used in the Solar Super Capacitor project.

    Super capacitors are also pretty "green" compared to batteries.

    That project also used a very nice weatherproof box by Hammond Manufacturing.

    Super capacitors were also featured in the Epishine Solar Cell road test.

    The Enocean system mentioned above also has very low power wireless communications - Enocean actually sponsored a design challenge where we got to try some of their solar cell powered sensors.

    My first venture into solar electric used a 12V car battery charging panel connected to a portable jump start pack which had a 12V 18Ah gel battery. It seemed to work well, the battery level indicator always showed full charge. However the weekend I really needed it during a storm power outage to power the freezer, revealed otherwise. The 'sealed' maintenance-free battery had gassed itself dry. So a solar charge control circuit probably would have helped there.

    Second more recent attempt was to use the same panel with a Waveshare solar power manager / powerbank
    https://www.waveshare.com/solar-power-manager-c.htm

    but so far its charge management electronics appears to drain the powerbank quicker than it can charge it. So not doing so well there either, but it's still usable as normal power bank and has the advantage of a solid metal case and user-replaceable 18650 cells. A larger / more efficient panel may help however. 

    Third attempt is with a Waveshare solar power manager
    https://www.waveshare.com/catalog/product/view/id/3659/s/solar-power-manager/category/37/

    connected to a 6V 2W Voltaic Systems panel and 3700mAh LiPo pack (can also take a 14500 on-board). This one appears to maintain steady state, never gets to full charge but doesn't drain either. Once again, a larger panel may help.

    Another important thing needed for a reliable solar system is the robust cabling from the solar panel to the inverter. Inadvertent grounds from cable nicks, insulation leakage/shorts to ground, or shorts from animals gnawing on the wire jacket is a recipe for problems.

    A watertight enclosure for your electronics is a good thing as well, if your solar project is a stand alone outside device.
