Installing lighting fixtures, especially outdoor lights can be expensive and tedious. But when you opt for solar powered lightings, you can save a lot by avoiding these things:
Electric charges - Solar lights are entirely powered by the free energy from the Sun, so you do not need to pay for any electrical usage.
Trench wiring - Most solar lighting systems come with their dedicated solar panels, so you do not need to run underground wire from the nearest electrical transformer to your lighting system.
Trenching - As no wiring is needed when installing solar lights, you do not need to dig trenches for your underground wiring.
Replacement landscaping - Because no trenching is necessary when installing solar lights, you do not have to replace and repair the landscape that is torn apart during the trenching process.
Replacement wiring - Due to age and weathering, your underground cables and fixtures will no doubt deteriorate over time. Since these things are located underground below your garden or within your landscape, you will have to do some digging and damaging to locate the fault and to replace them. Since solar powered lightings have their power source on itself, its very easy to locate and solve the problem.
