Running solar panels directly on a 250-watt sodium bulb is not feasible because solar panels generate electricity from sunlight, while a sodium bulb requires a specific electrical supply to operate. However, you can use solar panels to power an appropriate electrical system that can then supply energy to a sodium bulb, assuming you have the necessary inverter and battery storage to manage the power requirements. This setup would involve converting the DC output from the solar panels into AC power suitable for the bulb.
Yes, a ballast is required for a 250-watt sodium bulb. The ballast is essential for regulating the electrical current and ensuring the bulb operates properly. Be sure to select a ballast designed specifically for the type of sodium bulb you have.

Solar panels produce electrical energy when sunlight falls directly on them. The power of sunlight is about 1400 watts in every square metre and a solar panel converts some of that into volts and amps. Solar panels need direct sunlight falling face-on to produce a significant amount of electrical power. They also produce a very small amount of power when turned towards a bright sky without direct sunlight, and an even smaller amount on a cloudy day.
If you mean could you use the light from a bulb to energize a solar array or photovoltaic cell, the answer is yes. However the energy to run the bulb would exceed the energy produced by the array so you would have a net loss of energy in such a system.

One 25w solar panel for one 100w bulb. A 100-watt solar panel can produce about 400 watthours of power per day. A typical home consumes about 25,000 watthours per day. So you would need 62 one-hundred watt solar panels to run an average home.
The access panels to the light assemblies are the small rear corner panels of the storage compartments on left at right. After opening storage panels, you can pop out the rear corner panels--reach in, pull out the old bulb & socket, replace the bulb, reinsert the socket, then replace the panels, and you are done.

Yes, you can replace a 150 watt sodium bulb with a lower 70 watt sodium bulb. However, the lower wattage bulb may not produce as much light as the original 150 watt bulb, so you may experience a decrease in brightness. Make sure the 70 watt bulb is compatible with your fixture and follow all safety guidelines when replacing the bulb.
Yellow
The dominant color for a sodium street light bulb is usually a warm yellow or orange hue.
The 400W high pressure Sodium bulb contains a silver lining inside the frame to give better reflection of light. However, no silver is found inside the bulb.
