A home uses 5 kWh a day. The site gets 5 peak sun hours, system losses are 20%, panels are 400 W and the battery bank is 48 V with one day of autonomy at 50% depth of discharge.
| Step | Working | Result |
|---|---|---|
| Array size | 5 kWh ÷ (5 h × 0.8) | 1.25 kWp |
| Number of 400 W panels | 1,250 ÷ 400, rounded up | 4 panels |
| Battery capacity | 5,000 Wh ÷ (0.5 × 48 V) | ≈ 208 Ah at 48 V |
| Simple payback at ₹70,000 per kW and ₹8 per kWh saved | (1.25 × 70,000) ÷ (5 × 365 × 8) | ≈ 6 years |
Costs and tariffs are illustrative; real designs also check inverter size, cable losses and seasonal sunshine.
A turbine has a 40 m rotor diameter in an 8 m/s wind, with air density 1.225 kg/m³ and a power coefficient of 0.4.
| Step | Working | Result |
|---|---|---|
| Swept area | π × 20² | ≈ 1,257 m² |
| Power in the wind | ½ × 1.225 × 1,257 × 8³ | ≈ 394 kW |
| Power captured | 394 × 0.4 | ≈ 158 kW |
| Theoretical maximum (Betz limit 59.3%) | 394 × 0.593 | ≈ 234 kW |
Because power rises with the cube of wind speed, a site with 10% higher average wind gives about 33% more energy.
Tutors match your level, syllabus and exam board, from school to PhD.
| Level | What you study | Matching help |
|---|---|---|
| A-Level Physics | Energy resources and efficiency | A-Level AQA Physics and live tutoring |
| Undergraduate engineering | Energy engineering and renewable energy modules | Engineering Physics, homework help |
| Design projects | Solar, wind and efficiency projects | MATLAB and assignment help |
| Master's and research | Energy systems and policy research | Dissertation help |

Most lost marks come from unit errors and designs without economics.
| Mark-loser | What to do instead |
|---|---|
| Mixing kW and kWh | kW is power; kWh is energy |
| Ignoring system losses | Include losses in PV and wind sizing |
| Using the radius as the diameter | Swept area uses radius: πr² |
| Battery sized without depth of discharge | Divide by allowable depth of discharge |
| No economic analysis | Add payback, NPV or levelised cost |
| Out-of-date data | Use current resource and cost data |
Energy engineering is assessed in several formats, and each one is marked on different things. Tutors help you understand the brief and the marking criteria before you start.
| Assessment | What markers look for |
|---|---|
| Problem sets | Accurate energy and power calculations |
| Design projects | Sized systems with costs and justification |
| Energy audits | Measured consumption and ranked savings |
| Exams | Concepts and calculations |
| Reports | Technology or policy evaluations |
Energy engineers use these tools.
| Tool | What it is used for |
|---|---|
| PVsyst or SAM | Solar system modelling |
| RETScreen | Project feasibility |
| Excel | Sizing and economics |
| Energy meters and data loggers | Audits |
| HOMER | Hybrid microgrid design |
Energy engineering is taught to similar core ideas worldwide, but grading, referencing and course structure differ. FLN tutors work from your own syllabus and handbook and schedule lessons in your time zone. Always follow your module handbook for referencing.
| Country | Where energy engineering is studied | Grading | Referencing usually used |
|---|---|---|---|
| United Kingdom | Mechanical, electrical and energy engineering degrees | GCSE 9–1, A-level A*–E; degrees First, 2:1, 2:2, Third | IEEE or Harvard |
| United States | Energy and renewable energy engineering programmes | Letter grades A–F and a 4.0 GPA scale | IEEE |
| Australia | Renewable energy engineering degrees | HD, D, C, P at university; ATAR for school leavers | IEEE or Harvard |
| Canada | Energy and sustainable engineering programmes | Letter grades or percentages; GPA scales vary by province and university | IEEE |
| India | B.Tech/BE energy and renewable energy courses, with examples from India's solar and wind programmes | Board exam percentages; university CGPA, often on a 10-point scale | IEEE |
Students in Ireland, the Gulf, Europe, Africa and Asia can book the same help, with lessons in their own time zone.
The price of energy engineering help depends on the type of task and your deadline. A short calculation costs less than a full design project. You always see the price first: a fixed quote for homework and assignment guidance, or the tutor's hourly rate for live lessons, with no contract and no minimum number of sessions. Refunds follow our refund policy.
