Bluebird 40 Watt 12 Volt Polycrystalline Solar Panel
QUESTIONS & ANSWERSAsk a Question
Can we use solar panel without battery and inverter..?
You can use solar panels without batteries as they only provide backup and are necessary in offgrid installations
You can also use solar panels without inverter but only if your appliances are running on DC power and not AC
Frequently Asked Questions
Yes, solar panels work on cloudy days but generate less power due to low light availability. You can connect batteries with your solar power system to get power during cloudy days. It will offer you power at night.
You can use it to power your fans and LED lights, charge mobile phone and laptops, solar fencing purpose, home and business rooftops, camping.
With a bluebird 40W Polycrystalline solar panel you can easily run 2 - 3 LED bulbs of 10W Each.
You may need 9-10 no. of 40W Polycrystalline solar panels to charge a 150Ah battery.
Yes, Bluebird 40W Polycrystalline solar panel can be converted to AC solar panel / module by connecting a microinverter to this solar panel. This way your solar panel will generate AC power instead of DC power.
10A is sufficient in case you want to use one panel only. For future, in case you plan to buy one more panel, you can buy a 20A Charge controller also. Price difference is very nominal.
We suggest using a 12V inverter with a 12V battery with this solar panel. It is compatible with all inverter and battery brands.
Solar panels are manufactured with strict QC to ensure they perform well for a minimum of 25 years. So, if you find your panels are not generating power, it's more likely that the defect is in some other appliance like an inverter, charge controller, wiring, or batteries. Zero power output might be due to a faulty inverter or charge controller. It’s also possible that one solar panel in your solar photovoltaic array might have failed. One defective PV module can shut down the whole system when connected in series.
No current/ampere doesn't mean the solar panel is faulty. You will not get any current if your batteries are fully charged, and there’s no place for it to go. The current flow stops through the solar panel at Voc = Voltage Open Circuit. No current can flow in an Open Circuit. You are at an open circuit if your batteries are charged. Wait until the sun shines bright at noontime. Turn everything on, and this might solve your problem.
