'The same voltage' is the system voltage which for off-grid solar panels systems is usually as low as either 6V or 12V.
Why do solar panels have different wattage?
When connecting different solar modules, it's not the different wattage, it's actually the current (for series connection) and voltage (for parallel connection) that could drag down the performance of the solar array composed of those modules.

Are solar panels connected in series?
When you connect solar panels in series, the total output current of the solar array is the same as the current passing through a single panel, while the total output voltage is a sum of the voltage drops on each solar panel. The latter is only valid provided that the panels connected are of the same type and power rating.
Are solar panels rated higher than system voltage?
