Across 5. solar panels, which are used to produce electricity, are ? to set up 8. Also, the setting up of solar energy is ?. If the panels are going to be put on an already built surface(e.g a roof), some structures might have to be destroyed in order to construct solar panels. 9. reduces electrical bills as solar energy produces energy at a ? cost 10. solar energy is a ? source of energy

Down 1. solar energy is ? as the sun shines most of the time 2. electricity generated through solar energy reduces ? on electrical utilities 3. maintenance costs are ?. Maintenance costs are high.PV cells for example require frequent maintenance and in the case of a severe storm,there might be a need to arrange a professional to repair damage done to the panels 4. solar energy is not a very ? source off energy as there is no guarantee that the sun shines continuously as it is dependent on weather/climate 6. in conclusion, solar energy has both ? and disadvantages 7. solar energy does not ? the environment as it does not release any harmful gases in the production of electricity
