A basic PWM controller is a good start for small systems. Install the solar panel in a spot where it gets maximum sunlight. Connect the panel to the charge controller, and then to the battery. Use proper wiring and secure connections for safety. Initially, use your setup to power something small.
However, you can often build a photovoltaic solar installation without battery storage. Such “direct” or “direct-drive” solar systems are cheaper, quicker, and easier to make. A direct solar power system allows you to use a wide variety of appliances during the day, even powerful ones.
Here's how you can make the most of small solar panels: Choose the Right Panel Size: Understand the power requirements of your devices. A 10 to 20-watt panel is usually sufficient for charging small electronics or powering a light bulb. Positioning is Key: Maximize solar intake by positioning your panel where it gets the most sunlight.
But if you'd like to start dipping your toes in the renewable energy waters, so to speak, it is possible to put together smaller solar systems that can provide at least some of electricity you need on a daily basis.
Put a fuse in between. Optionally, add an on/off button. Make sure the device you power can take the voltage that the solar panel supplies to it. If your direct solar PV system has a DC-DC converter, connect the plus and the minus of the solar panel to the plus and the minus of the DC-DC converter input.
Power (watts) = V (volt) x A (ampère) Omitting the inverter has lots of advantages. First, it makes solar installation cheaper because inverters are expensive. Second, it makes the solar power system more energy efficient.

The power produced by solar panels can vary depending on the size and number of your solar panels, the efficiency of solar panels, and the climate in your area. How many solar panels are needed to run a house?
Before sizing a solar array, it helps to know a few key terms: Watt (W): measures power. A solar panel rated at 300 W can deliver that amount under optimal sunlight. Kilowatt-hour (kWh): a unit of energy equal to 1,000 watts for one hour. For instance, a 300 W panel producing peak power for four hours generates 1.2 kWh that day.
Wattage refers to the amount of electrical power a solar panel can produce under standard test conditions (STC), which simulate a bright sunny day with optimal solar irradiance (1,000 W/m²), a cell temperature of 25°C, and clean panels. In simpler terms, a panel's wattage rating tells you its maximum power output under ideal conditions.

12V panels are often used for small solar setups because they are compatible with 12V battery systems, which are common in RVs, boats, and off-grid applications.
Open circuit 20.88V voltage is the voltage that comes directly from the 36-cell solar panel. When we are asking how many volts do solar panels produce, we usually have this voltage in mind. For maximum power voltage (Vmp), you can read a good explanation of what it is on the PV Education website.
The best choice among these three depends on the size of the system. 12V is perfect for small solar systems like in RVs and trailers, 24V for medium size ones like a small home or cabin, and 48V is ideal for large home systems. The higher your power needs, the higher the voltage you should use.
Voltage output directly from solar panels can be significantly higher than the voltage from the controller to the battery. Maximum Power Voltage (Vmp). The is the voltage when the solar panel produces its maximum power output; we have the maximum power voltage and current here. Here is the setup of a solar panel:
This might sound weird, but both are correct and useful: Nominal 12V voltage is designed based on battery classification. With solar panels, we can charge batteries, and batteries usually have 12V, 24V, or 48V input and output voltage. It is the job of the charge controller to produce a 12V DC current that charges the battery.
To be more accurate, a typical open circuit voltage of a solar cell is 0.58 volts (at 77°F or 25°C). All the PV cells in all solar panels have the same 0.58V voltage. Because we connect them in series, the total output voltage is the sum of the voltages of individual PV cells. Within the solar panel, the PV cells are wired in series.
Since optimal conditions are impossible to achieve at all times, I usually recommend to estimate a 70-80% efficiency when calculating how much solar you need for a specific application. Knowing the wattage helps in selecting the right solar panel for your needs and ensuring it can handle the load of your intended applications.
